memory leaks - tools and docs

[Aljosa Mohorovic]

i've been trying to find memory leaks in a wsgi application using
gunicorn to run it and after a lot of time invested in research and
testing tools i did find a lot of useful information (most really old)
but i'm left with a feeling that this should be easier, better
documented and with tools that generate better data.

if anybody can share some tips, links, docs or better tools with
better reports i would really appreciate it.
i'm not against paying for a good tool so any recommendation is
appreciated.

i mostly used http://guppy-pe.sourceforge.net/#Heapy but found
http://pysizer.8325.org/ and http://code.google.com/p/pympler/ also
interesting.
