(Note: The following applies to Perl threads only, not to system-level threads in general)

As near as I can decipher from your post, the lexicals are thread private.

Each Perl thread gets its own Perl interpretter. When a new thread is spawned, it gets a cloned version of the parent's Perl interpretter context (w/ some minor exceptions). Which means any lexicals in your package will simply get cloned, not shared, between the threads.

If you need to share variables between threads, you must explicitly declare them to be shared. See threads::shared.

Alas the only book I'm aware of that covers the subject is the Camel 3E, and its (a) quite dated and (b) not a very thorough discussion. There have been some articles on the subject, but I believe most of them are fairly dated at this time as well. I've not checked the latest editions of Learning or Mastering, so I don't know if they discuss ithreads.
