[issue22336] _tkinter should use Python PyMem_Malloc() instead of Tcl ckalloc()

[STINNER Victor]

STINNER Victor added the comment:

I read tkinter_pymem_2.patch.

Remaining calls to ckalloc():

* they are only used to allocate events passed later to Tcl_ThreadQueueEvent(). Tcl_ThreadQueueEvent doc explicitly says that the memory must be allocated by Tcl_Alloc or ckalloc, so it's correct (PyMem cannot be used).

Remaining calls to ckfree():

* Tkapp_SplitList() calls ckfree() on memory allocated by Tcl_SplitList(), it's correct.

* Tkapp_CallDeallocArgs() ckfree() on memory allocated by PyMem_Malloc() => wrong (see my review on Rietveld).
