I believe 4DOM uses cyclical references, and requires that you always
call a .releaseNode() method to break the cycles.  So, you could just
try running 4DOM and never calling .releaseNode(); with the GC, it
shouldn't leak.  The old PyDOM code tried to avoid creating cycles, so
it wouldn't make any garbage to be collected (modulo bugs).
