That's fine, and it's a lot different from calling for "someone with
muscle" to step in so that "we can have tools that do what [you think] they
are supposed to do".

On lots of platforms, the stack and heap come out of the same pool, so
there's no distinguishing "tight heap" from "tight stack".

Well, allocators could be used to make preallocated memory available, if
that's your preferred solution. As I said before, I'm not convinced it's
the right answer, but I don't see why it's neccessarily wrong (yet),
either.
