Dan, I have bet the software barn on two things occuring: (1) Perl threading and regexp working properly. (Else--why use threaded perl at all?) (2) Perl threading getting more efficient. One is must-have, two is would-be-nice. I'll add a comment before I start a war. For what I need to do, the best thing about perl is its regexp parser, which is more full-featured than anything else I can find. It's speed is good too, which is critical. When I needed to structure my code to simultaneously parse multiple streams, I could have either (a) rewritten my perl objects in C++ (starting over) or (b) made use of perl's threading mechanism, and kept most of the code base. I did the latter, even though threading was listed as experimental. I plan to work to help make the next version of perl threading work, and we have committed some resources to help make that happen. Next Question: Will somebody knowledgeable about the debugger fix the perl debugger as I described in bug report [ID 19990820.008]? I even included a simple test case... I desparately need a working debugger in the threaded environment; adding print statements is getting wearisome.
