duh...if my collect is AFTER the method terminates, there is no root.  
I now have a ROOT when I walk!  Woohoo!  I haven't done C/C++ in 13  
years...woof...finally rediscovered nm to tell me about extern  
symbols...that chain root is essentially binding to the ptr in my GC.c  
file. :)  I get some output from my collector now:

process_root[0x0xbfffed08] = 0x0x800000

Now to figure out what to do with these suckers ;) and make it  
actually collect!
