threaded RTS uses SIGALRM

The threaded RTS uses SIGALRM for its timer signal, this is a bit naughty and could interfere with use of SIGALRM by the application. Also it can cause EINTR of system calls, which the application might not be prepared to handle. Some system calls can't be reliably restarted (eg. usleep()).
The single threaded RTS uses SIGVTALRM, but we can't use this in the multithreaded RTS because it ticks in CPU time, and our threads might be idle. Ideally we should be using the timer_*() family of functions, if supported.
