"""Memory debugging helper.
Using this module:
1. at the beginning of your program import this module...
from application.debug.memory import *
2. call memory_dump() later, when you want to check the memory leaks
Note: when debugging for memory leaks is enabled by the inclusion of
this code, the garbage collector will be unable to properly free
circular references and they will show up in the garbage objects
list (this will make the application constantly grow). However
if this code is not loaded, the garbage collector will properly
detect and free the objects with circular references and the
size of the application will remain constant even in the
presence of circular references.
