Much of the confusion in this thread comes from the murky distinction
between "garbage collection" and "memory management." I wouldn't call a
reference-counting system "garbage collection" per se.
Another bone of contention seems to be the question exactly WHEN
reference counting and/or garbage collection release an object's
resources (give it back to memory management). I read the word "when" in
the non-implementation-specific Python docs as "immediately upon" (quote
below, caps by me):
"Note: del x doesn?t directly call x.__del__() ? the former decrements
the reference count for x by one, and the latter is only called WHEN x?s
reference count reaches zero."
It is then up to Python's memory management (PyMem_Alloc et al in
CPython) what to do, and when: Give it back to the OS, keep it around
for later use, whatever.
