Dumping references

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

    I've been trying for several days now to track down why some of my
objects fail to be GC'ed until lua_close().  As far as i can tell they have
no other references, yet they refuse to be collected.  So in order to figure
this out i think i've got to build myself a diagnostic function which dumps
enough information about the references to an object that i can pin point
the problem.  Has anyone attempted this before and is this the direction i
should take?  Also i'm sure some of you must have run into similar
situations... any other suggestions to track down this issue?  Thanks.
