The workaround I've settled for uses the shelve module and calls to gc.collect() to put a cap on the amount of memory the Python allocator consumes. A bit more intrusive but it gets the job done.
Would a gc method that released memory to malloc be something worth adding to Python? Or are there reasons why allowing this is a bad idea?
