Are you open to doing something other than pthreads? Using fork() to get real processes, and then sending a SIGSTOP (and SIGCONT) to the one running main() should work. Or emulating the interrupt arrival with a signal, and having interrupt_handler() be registered as the signal handler. Of course, you then have to deal with the constraints that come with signal handlers, so that can be a bit of a pain depending on what you're trying to do.
