however, patients are not allowed to initiate bisphosphonate therapy within 4 weeks prior to starting therapy or throughout the study * Prior radiopharmaceuticals (strontium, samarium) must be completed at least 8 weeks prior to treatment initiation in this study and all major side effects resolved to =\< grade 1 * Patients receiving any other hormonal therapy, including any dose of Megestrol acetate (Megace), Proscar (finasteride), any herbal product known to decrease PSA levels (e.g., Saw Palmetto and PC-SPES), must discontinue the agent for at least 4 weeks prior to enrollment * Life expectancy of at least 12 weeks * Written informed consent/HIPAA (Health Insurance Portability and Accountability Act)authorization must be provided prior to the performance of any study-related procedures Exclusion * Prior treatment with AVASTIN, temsirolimus, everolimus or sirolimus * Evidence of current or prior central nervous system (CNS) metastases or any imaging abnormality indicative of CNS metastases; patients with history of cord compression are eligible provided they had either palliative radiation therapy or surgery, have NO neurologic symptoms (as determined by treating physician), have stable spinal disease by scans and are off any steroids prior to initiating study drug (at least 7 days) * Major surgery or radiation therapy within 28 days prior to screening (Palliative radiotherapy to painful bone lesions is allowed within 14 days prior to study entry); subject must have recovered from prior surgery and radiation * Significant cardiovascular disease defined as congestive heart failure (NYHA Class II, III, or IV), angina pectoris requiring nitrate therapy, or myocardial infarction within the last 6 months * Inadequately controlled hypertension (defined as a blood pressure of \>= 150 mmHg systolic and/or \>= 100 mmHg diastolic on medication), or any prior history of hypertensive crisis or hypertensive encephalopathy * History of stroke or transient ischemic attack within 6 months prior to screening * Significant vascular disease (e.g., aortic aneurysm, aortic dissection), or symptomatic peripheral vascular disease * Known congenital long QT syndrome, history of Torsade de pointes or ventricular tachycardia * Known pulmonary hypertension or pneumonitis * More than 1 episode of DVT/PE within the last 6 months * Evidence or history of bleeding diathesis or coagulopathy * History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within 6 months prior to screening * Supplements or complementary medicines/botanicals are not permitted while on protocol therapy, except for any combination of the following: conventional multivitamin supplements; selenium; lycopene; soy supplements; patients should review the label with their doctor prior to enrollment, and discontinue disallowed agents prior to study enrollment; patients taking St. John's Wort need to discontinue its use at least 7 days prior to initiating trial * Serious intercurrent infections or non-malignant medical illnesses including uncontrolled autoimmune disorders * Psychiatric illnesses/social situations that would limit compliance with protocol requirements * Known contraindication to receive temsirolimus or AVASTIN * Use of any other experimental drug or therapy within 28 days of baseline * Immunocompromised subjects, including known seropositivity for human immunodeficiency virus (HIV), or current or chronic hepatitis B and/or hepatitis C infection (as detected by positive testing for hepatitis B surface antigen \[HbsAg\] or antibody to hepatitis C virus \[anti HCV\] with confirmatory testing) (testing is not mandatory to be eligible for the study) * Anticancer therapies such as biologic therapy and chemotherapy, as well as radiation therapy or cancer surgery * Other current or recent (within 4 weeks prior to randomization) investigational agent * Rifampicin * Immunosuppressive therapies except steroids * Prophylactic use of white blood growth factors to support neutrophils * Concomitant treatment with agents that have CYP3A4 induction or inhibition potential should be voided
