.. and that may not be true on a grow-up stack. Christ, that code is
hard to read. But I think Kirill is right, and I'm wrong.
So that "try to expand" code is only ok when non-overlapping, or when
moving down.
Naresh - from a testing standpoint, that doesn't make any difference:
I'd still like you to test on x86. We always shift the stack down
there.
