8.16: How can I sleep() or alarm() for under a second?

    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" in perlfunc. Try the "Time::HiRes" and the
    "BSD::Itimer" modules (available from CPAN, and starting from Perl 5.8
    "Time::HiRes" is part of the standard distribution).

are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
