You will want to have a look at the Time::HiRes module - This module exports alternate `alarm`, `sleep` and `time` methods which allow timing with a greater level of precision. Additionally, this module provides `ualarm` and `usleep` methods for providing such timing precision measured in microseconds. See the man page for this module for examples of usage.

This is a faq "If you want finer granularity than the 1 second that the sleep() function provides, the easiest way is to use the select() function as documented in "select". Try the Time::HiRes and the BSD::Itimer modules (available from CPAN)." -- Until you've lost your reputation, you never realize what a burden it was or what freedom really is. -Margaret Mitchell	[reply]

You can effect a sleep of 250 milliseconds this way: `select(undef, undef, undef, 0.25);`	[reply] [d/l]
