[OT] finding memory hungry bits of my code

If there is something out there that does for perl memory usage analysis 
what NYTProf does for profiling, then I am >dying< to get my grubby 
little hands on it.

My ideal tool would give me a breakdown of the memory used by current 
SVs by package.  Not sure if I'm saying that right or if this is even 

The problem I seems to face twice a year is that some hash somewhere 
that is declared in package scope or in the lexical scope of a file is 
being used as a cache and that cache's size is getting too big.  I don't 
know of a programatic way to identify the problem hash.

Anybody know of a magic tool that does what I'm after?  Or maybe you 
know of a way to walk all things declared in package scope or the 
lexical scope of a file?
