finding memory leaks in perl objects
This module provides tracking of objects, for the purpose of detecting
memory leaks due to circular references or inappropriate caching schemes.

Object tracking can be enabled on a per object basis. Any objects
thus tracked are remembered until DESTROYed; details of any objects
left are printed out to STDERR at END-time.

Of particular interest is 

use Devel::Leak::Object qw{ GLOBAL_bless };

which overrides CORE::bless to give a full tally of all objects at END {}.
