[distcc] bug in mon-text

[Ron Van Iwaarden]

Within mon-text, there is the comment that usleep is not very portable.  
I did run into a bug with this on an SGI.  usleep for values greater 
than 1 second (values over 1000000) returns immediately.  I replace the 
code usleep(value*1000000) with:

if (delay < 1){
    usleep(delay * 1000000);
}
else{
    int d2 = (int) delay;
    sleep(d2);
    double fraction = delay - d2;
    usleep(fraction * 1000000);
}


which works very well.
