    Use timer_create() for the interval timer, if available · e30aca19

    This lets the threaded RTS use SIGVTALRM rather than SIGALRM for its
    interval timer signal, so the threaded and non-threaded RTS are
    compatible.  It unfortunately doesn't completely fix #850/#1156, for
    that we really have to use a restartable sleep instead of usleep().
    Also I cleaned up the timer API a little: instead of returning an
    error value that ultimately gets ignored, we now report errors from
    system calls and exit.
