And you're only saying that because you work on a platform that has 
lousy thread support   Sorry, couldn't resist

Seriously, can anyone recommend a good tutorial on IPC for Perl/Unix? Is 
there a straightforward way for two processes to share a set of variables?

I've always avoided anything beyond a 'system()' or `backticks` strategy 
because all the Unix/POSIX IPC methods look like such a PITA.  Pipes are 
useless for two-way IPC; the SysV stuff looks seriously clunky (to my 
simple mind) and none of these allow you to easily share an actual data 
structure (a Perl hash, lets say), without jumping through all kinds of 
hoops.

Pardon my off-topic ignorance; take it off list if you wish.  I'm just 
fishing for a clue
