I’m unclear on why the sub-interpreter API exists and why it’s used in modules such as the mod_wsgi apache module. Is it mainly used for creating a security sandbox for different applications running within the same process, or is it a way to allow concurrency with multiple threads? Maybe both? Are there other purposes?

Given the absence of a Windows fork() call, how’s the multiprocessing package in Python 2.6 implemented under Windows? On top of Win32 threads or some sort of fake fork or just compatibility on top of the existing multithreading?
