Perl threads are currently "experimental". See README.threads for more info. Most likely, you don't want to use perl threads for anything but research. This will get better, but it's not there as of now.

See LWP::Parallel for a non-threaded solution to pulling webpages in parallel.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
