I am going to try and keep this journal to keep you readers uptodate with my struggle on the iThread module.
I needed a way to share cache data between perl interpreters, I needed this to be fairly platform independant and didn't want to play with IPC.
Given the fact that perl has the capability to run multiple interpreters in different threads, and that Sarathy has said this shouldn't be an impossibility to expose to the perl level, I decided to give it a try.
There is a mailing list for the effort, to subscribe mail to perl-ithreads-subscribe@perl.org
I will mail updates of the code to there, I am also going to get a CPAN account, you can usually also find me on irc.infobot.org #perl as sky
