Tracking down a GC problem

["Tom Spilman" <tom@...>]

    I'm in a situation where *alot* of tables and userdata are not collected
until my app exits.  The problem is my app is large enough that i've not
been able to quickly figure out which tables and userdata that is.  My first
thought was to walk the globals table and dump the content to hopefully
identify the data and what code generates it.  Still it would be better to
track exactly where the tables and userdata in question are being allocated.
Any suggestions on how to go about doing this (preferably from within a lua
script)?
