calling gc.collect() doesn't change the memory usage.
(Dan's patch is applied)
obj_list = []
for i in xrange( 1000 ):
obj = SomeObject( parameters ... )
obj_list.append( obj ) # memory grows
for obj in obj_list:
obj.expire() # clear cache
del obj_list
gc.collect() # <- added here, memory usage doesn't change.
