[San-Diego-pm] A few questions of Perl

1. I would assume, (possibly incorrectly) that using the Socket or
IO::Socket modules would provide the inherent ability to open more than one
tcp socket for send/receive. Although i could see being limited in having
more than one [socket bound to a] filehandle open, there are always a
billion ways to do something in perl.
2. I've seen someone do a sleep(undef, undef, undef, 0.2); to wait a
quarter-second, but i can't confirm it works.
good luck :)
