I try to avoid threads ATM except when running ActiveState Perl on
Windows which is compiled with threads.

I've never seen that one. Have you reported this error in CPAN's bug
tracker?

What's the output from `perl -V`?

I've done a bit of research on this issue. My understanding is that this
was true for the original implementation of threads but that the newer
version should make all modules thread-safe by default[1]. I'd be
interested to hear from someone who has more experience.


Good luck,
