That perlmod link is not terribly useful. For instructions on creating per-interpreter variables, see "Safely Storing Static Data in XS" in perlxs. It even includes an example.

The mechanism allows each interpreter in a process to have their own copies of variables. This is useful not only when threads are involved, but in all instances when a process has multiple Perl interpreters (e.g. mod_perl?).
