[Python-Dev] FS: [issue9141] Allow objects to decide if they can be collected by GC

[Kristján Valur Jónsson]

Hi there. Antoine Pitrou suggested that I float this on python-dev again.  The new patch should
1) be much simpler and less hacky
2) remove the special case code for PyGenObject from gcmodule.c

Efni: [issue9141] Allow objects to decide if they can be collected by GC

Kristján Valur Jónsson <kristjan at ccpgames.com> added the comment:

Here is a completely new patch.  This approach uses the already existing tp_is_gc enquiry slot to signal garbage collection.
The patch modifies the generator object to use this new mechanism.
The patch keeps the old PyGen_NeedsFinalizing() API, but this can now go away, unless people think it might be used in extension modules

(why do we always expose all those internal apis from the dll? I wonder.)
