poll() in Solaris iomgr.c computes timeout incorrectly

    if (timeout > 0) {
        timeval_t tv;
        tv.tv_sec = timeout / 1000;
        tv.tv_usec = timeout % 1000;
        time_limit = currentTime();
        timerAdd(&time_limit, (timeval_t *) &tv);
    }

The above piece of code from iomgr.c sets tv.tv_usec incorrectly. timeout is in
milliseconds, but tv.tv_usec needs to be in microseconds.
