Hi all, Possibly of interest to some folks here, it looks like in Python 3.4 there'll be a generic system for hooking and tracking memory allocations: http://www.python.org/dev/peps/pep-0445/ I'm not planning to do anything with this information myself, but if anyone's been thinking about numpy memory profiling, the new numpy malloc hooks, etc., then it might make sense to see how we could integrate with this more general system. -n
