If they are Python modules, more or less, yes. Extension modules
cannot currently be finalized (I plan to change that for Py3k).
See PyImport_Cleanup for the precise algorithm used; there are

Absolutely. This is exactly what I did in my "interned" patch and this

I don't feel that way; dict is more basic, set is just a special case of
dict for performance reasons. Also, dict is used to define and implement
the language itself, set is "just" a predefined type.

I have not been bitten by the other _Fini yet. ;-)
I was bitten by PySet_Fini when I tried to replace the "interned" dict with a
set. Sin

given that CPython has about a dozen Fini
Setobject code allocates several internal objects on the heap that are
cleaned up by the PySet_Fini function. This is a fine design choice,
but it often makes debugging applications with embedded python more
difficult.
I propose to eliminate the need for PySet_Fini as follows:
1. Make dummy and
14 matches
