Hi Jason.  I've tried importing a large scan (via XML) into Zenmap and
it too hangs, consumes all the memory and then gets killed by the OOM
killer.  I don't think it is a memory leak, just what you get when you
try to keep 2^14 objects in memory in a language like Python (or Perl
or Ruby or Java...).
