I was just about to do the same to usleep() when I found a problem.  
usleep() has a void return, so there's no way to indicate an interrupted 
usleep().  Both sleep and usleep were coded the same way, ie: sit in a 
while loop waiting for interrupts until the sigalarm happens.  is usleep() 
supposed to wait the full time even if interrupted?  or is the application 
supposed to do a gettimeofday() to determine how long really passed?
