Yes, this is obviously a good idea, but we need a program to sort
the logfiles into "everything looks sane" and "something looks out
of pattern" before we can really benefit.

Yes, we should do that, but considering how little memory management
we actually do, we should not spend too much time.  There are there
are less than 50 places where memory is actually allocated in the
