This is an interesting point, and I did the test.

Making some searches leads me to:
http://stackoverflow.com/questions/1316767/how-can-i-explicitly-free-memory-in-python

Memory can be cleaned manually by calling garbage collector.
>>> import gc
>>> gc.collect()

Maybe this could be called by a cron task ?
