I have a program that creates a huge (45GB) defaultdict. (The keys are short strings, the values are short lists of pairs (string, int).) Nothing but possibly the strings and ints is shared.
That is, after executing the final statement (a print), it is apparently spending a huge amount of time cleaning up before exiting.
I have done 'gc.disable()' for performance (which is hideous without it)--I have no reason to think there are any loops.
