Re: Collecting dead strings

["Research" <research@...>]

I tried setting foo and fooTable to nil too, and after I call 
lua_setgcthreshold(L, 0) there still seems to be some strings allocated.

Is there a simple way to traverse the entire registry and globals table to 
dump it out and see what's in there from C?
