Looking in the manhole for memory leaks..

import gc, sys
objs = []
for obj in gc.get_objects():
    size = sys.getsizeof(obj, 0)
    if size > 1024:
        objs.append((obj, size))

objs.sort(key=lambda x: x[1], reverse=True)

from pprint import pprint

print len(objs)  # total objects
print objs[0][1]  # largest object size
pprint(objs[0][0])  # largest object
print objs[1][1]  # second largest object size
pprint(objs[1][0])  # second largest object
