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!
