I am trying to sleep at the microsecond level, which ssleep and msleep 
cannot provide.  I couldn't find any other nanosleep method in the kernel.

I found information by searching the net on using jiffies to accomplish 
sleep periods, but that is not high enough in resolution.

I'd greatly appreciate any feedback.

Thanks!
