perlthrtut is almost completely useless as a starting point on how to use iThreads.

Things you need to know before programming Perl ithreads (which I refuse to link), describes a situation circa. v5.8.0 (the first ever iThreads build) & v5.8.1 (the buggiest threaded perl build ever, that lasted a whole 41 days before being superceded), from the perspective of someone who attempted to emulate iThreads with forks--and failed. Update: Are you going to refer newbies to Things you should need to know before using Perl regexes. (Humour, with a serious point) when they ask about regexes?

And, in the process succeeded in littering the entire cpan Thread::* and (as I recently discovered) thread::* namespaces with over-ambitious, unsupported (and almost unsupportable), mostly defunct, and do nothing modules that are in great part the cause of the difficulties that people have trying to use iThreads, (Now sadly billed as the "greatest authority on Perl threading"!).

Finally, how about you try writing a POE solution before you recommend it to others on the basis of hearsay.
