sleeping less than a second

We get this question enough to make a faq article.

I like to use select() for this. These threads discuss using a perl one-liner.
Sleep less than 1 second
Anything smaller than sleep 1
And a C implemention: nodoff

And see: How do I sleep() in a C program for less than one second?

Also in ksh93, but not ksh88, sleep is a built-in that can accept a floating point argument. Example: "sleep .25" will sleep for 1/4 of a second.
