[Python-Dev] Proposal to eliminate PySet_Fini

[Alexander Belopolsky]

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 emptyfrozenset static objects similar to Py_None
2. Eliminate the free sets reuse scheme.

The second proposal is probably more controversial, but is there any
real benefit from that scheme when pymalloc is enabled?
