when running this script:
aList = []
for i in xrange(5E5):
    aList += [[]]
    for j in xrange(10):
        aList[-1].append([])
del aList

It does not give back the memory

even a

import gc
gc.collect()

afterwards does not do it.

In Python 2.5 the memory is freed again correctly, at least under Windows.

The problem came up, because I was parsing a CSV file of 50 MB which
resulted in memory usage of more than 500 MB.
