it may be that there is something non-deterministic about certain
instances of problems, especially in sort/ordering cases when pointers
are compared which may happen to be ordered differently on different
systems.  but of course correct code should never trigger an assertion.

i hope not, given that we're already using it on Linux; it should only
find "new" problems in Mac/WNT-only code.   well, WNT-only code at this
point, since Stephan already reverted it on Mac.
