SIGSTOP stops all threads, i.e. the process AFAIK.

The best way to implement suspend is to not do it.  Every threading
api that has implemented suspend/resume has either deprecated it or
has warnings not to use it.  It's basically useless except as a
mechanism to introduce race conditions.  And there are a lot easier
ways to create race conditions.  What is it that you are trying to
to incorrectly?
