No, mod_perl 2.0 assign a "full" Perl interpreter to every Apache thread. So
the Perl modules itself need not to be thread safe. Perl 5.6 has some nice
features to clone a Perl interpreter in a efficent way (syntax tree of
modules (loaded before clone) is used by all cloned Perl interpreters, while
the data is separate for all cloned Perl interpreters). mod_perl 2.0 get
manages a pool of cloned Perl interpreters which is assigns as neccessary to
the Apache threads.
