FYI, Gurusamy Sarathy did a lot of the debugging to make perl ithreads
almost work about 5 years ago. ActiveState needed reliable threads
for their mail filter (milter) product written in Perl.
He did a couple of great talks on that at the Perl Conference in San Diego.
The result worked well enough that Sophos bought ActiveState for
that product, he became CTO, and then Sophos spun off the tools group
into the new ActiveState.
So I guess the lesson is try the latest Perl, and if threads still
don't work, man up and fix it, or try something else. :)
