what magic do you expect the "manual garbage collection" to do here thatThe DECREF decrements the reference count, but does not immediately prompt
the DECREF doesn't already do?
garbage collection when the reference count drops to zero; that garbage
collection does not appear to occur until I return from the particular C
function I am in the middle of executing.
Ideally, I want to explicitly prompt garbage collection in the middle
of a C function, without first returning to the larger Python interpreter.
