1) I just downloaded the threads module from CPAN (associated with your name) a few days ago. Is ther a way to confirm that I have the correct one? 2) I understand that other non-Perl modules may not be thread-safe. By the time I get to the logic that is executed by the threads I no longer need the parent context where the 'Documents' and other strings were referenced. Is there a way to isolate the prior context (or quiesce it) before initiating the execution of the threaded logic? For instance is there a practical way of dividing the processing up into two steps in Perl so that the step 1 context is discarded before starting the multi-threaded step?
