See http://www.codeproject.com/cpp/garbage_collect.asp.  I also started 
a comparison
of this and other gc methods in boost, but never got around to finishing 
the html
files.  I could upload these if you wouldn't mind the incompleteness.  They
do outline some of the memory and time uses; however, its pretty dry 
reading.
