in thread Printing to STDERR causes deadlocks.

FWIW, this code works fine for me, with and without tracing, on perl 5.8.1 a 2 CPU 2GHz G5 mac with a 20MB text file (696k lines).

Update: That reminds me. If your perl is ok, suspect pthreads. I've seen some majorly broken Linux versions (not sure what you're using).

    Thanks bluto. 5.8.1 had many other problems with threads. Maybe fixing those problems touched this, or maybe it is just the different implementations on mac/osx versus win. This stuff has been so little exercised that there is probably no way to tell.

    I no longer have 5.8.1, but I've tried various size files on 5.8.4, 5.8.5 and 5.8.6 without success:(

    I also tried using the two arg version of cond_wait(), but I'll admit to not understanding how that's meant to work at the Perl level anyway.
