If you want to see if you have memory leaks try to run your code in an
infinite loop:
while 1:
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
and monitor memory usage. If it only increases once while the first pool
of 1000 objects is created, but then stays constant you are fine. I means
that the memory is not returned to the OS but reused for the next bunch
of 1000 objects and so on. If it constantly grows you have a mem leak.
