The one issue that I know exists in FreeBSD is we've had known problems
with threads for the longest time ... is it possible that the problem is
in milter itself? Not even necessarily spamass-milter, but milter itself?
If we are going to concentrate on the perl side of things, in spamd, what
would it take to do:
$msg = <STDIN>;
INstead of:
$_ = <STDIN>;
A friend of mine mentioned that there have been issues with using $_ in a
forked environment ... ? Something about $_ being global, even if
declared local?
