This commit continues the work started in commits521473eeande84fd464that parallelizes certain geometric operations. This commit cleans up the temporary arena implementations and makes them thread-safe. Also, in commit521473ee, a call to FreeAllTemporary() was added during initialization to create the heap on Windows. This is now not necessary as the heap is created transparently on the first call to AllocTemporary().
