[Python-Dev] extremely slow exit for program having huge (45G) dict (python 2.5.2)

[Kristján Valur Jónsson]

I'd like to suggest here, if you are giving this code a facelift, that on Windows you use VirtualAlloc and friends to allocate the arenas.  This gives you the most direct access to the VM manager and makes sure that a release arena is immediately availible to the rest of the system.  It also makes sure that you don't mess with the regular heap and fragment it.

Correct.
