If you are using sleep from GNU coreutils, you can pass decimals as argument. Like this:

sleep 0.1

All Linux systems should have this version of sleep. If your code needs to run on BSD and other *NIXes too I would encourage you to write the script in a language like perl, python or ruby which has something like usleep().
