Perl 5.8.1 (only) has bad random number initialisation when
forking leading to predictive random numbers, which is bad
for mod_perl and other things.
Only affects Fedora Core as we haven't shipped 5.8.1 in other distributions.
the 5.8.1 in fedora core 1 is patched against this
perl -le 'fork; print rand'
prints different numbers in fedora, but not stock 5.8.1
Looks like it is patched in FC1 and does not affect other releases.
