That's not the way it usually works. If you run out of memory, you

FYI you're violating someone's request by responding to them in a way
that results in it getting onto python-list, so it's probably safest
to just ignore cranks and trolls and let them stew in their own
juices.

But normally the GC doesn't need to be scheduled at all. In CPython,
the only reason to "run garbage collection" is to detect cycles, so
you would have to be generating inordinate amounts of cyclic garbage
for this to matter at all.
