There's another one in reversemenucomplete() which needs just the same
treatment.  I'd just made a patch for both, I can't be bothered to
extract the second one.

I was going to make the comment that all these permalloc()'s and so on
buried deep inside the code give me the screaming heebeejeebees (or
whatever it is you're supposed to get).  We really need to upgrade
permalloc(), heapalloc() and lastalloc() to use a stack, so we can
have matching heapalloc()/lastalloc() pairs at any depth in the code,
and these functions get called only when they're actually needed.
Then you have to manage the allocation of this stack, of course.
