You are not going to be able to do this without coding up some kind of
"delay loop" yourself.  Of course that solution is definitely NOT portable in
any way since the loop would have to be fine tuned to your machines execution
speed.  Remember that in the UNIX kernal, scheduled wakeups occur at fixed
one second intervals.  Thus, unless you are using a non standard kernal, sleeps
of only whole numbers of seconds are possible!
