Thanks for the great work! (And kudos to OpenBSD guys as well :^)

BTW, with regard to this work, I'm curious about how per-thread stacks
in the multithreaded apps are protected from being executed, especially
on i386. Both _lwp_create(2) and clone(2) require user-supplied stacks
as arguments, so there's currently no way to make them non-executable.
