  AAArrgh!  It's a Rational tool!  Oh no, run away!

  Maybe we should try and port the free open-source equivalent valgrind
(http://valgrind.kde.org/) instead?  I haven't ever looked at this, but it ought
to be possible.  I note that you can use (a special variant version of) valgrind
to verify win32 apps running on WINE.  So I guess there's a long-way-round to do
that already....
