--- Comment #9 from Mark Johnston <markj@FreeBSD.org> ---
As a follow-up, I've been working on a change to the way the stack gap works:
rather than maintaining a fixed address for the top of the stack and including
the gap against the RLIMIT_STACK limit, I changed the ELF image activator and
exec_copyout_strings() to locate the stack below a randomized gap.  This way,
the RLIMIT_STACK implementation requires no knowledge of the stack gap.
