Hi Marvin,
Lingua-Stem-Snowball is still not thread safe because the defined
$stemmifier variable (object) is (possibly wrong) cloned in to a new
thread.
To prevent this put these two sub's in to Lingua::Stem::Snowball.pm
# called in the context of a new thread to receate the home Stemmifier
sub CLONE {
$stemmifier = Lingua::Stem::Snowball::Stemmifier->new;
}
# called before cloning to destroy the parent home Stemmifier
sub CLONE_SKIP {
undef $stemmifier;
}
Best regards
Thomas
