I am reading up on using threads and in the past I know there have been issues with stability, speed, etc. So I need to get a few things cleared up.

1. The most recent documentation for threads.pm states that variables are by default thread local? I have also read that everything gets copied over to a new thread. Which is it?
2. I am reading that sharing data between threads is slow. Is this true? One of the main purposes for my application will be to share data between worker threads.
