Possibly.  If your milter process is dying with signal 6, then r1.61
wil most likely fix it (the code ends up throwing an uncaught exception
and abort()ing).  Beware that CVS versions 1.62 and above sometimes
leak processes due to my use of popen() to call "sendmail -bv" (I don't
think popen and pthreads play nice together); I'm trying to figure out
where the bug is.

This looks fine; LinuxThreads uses one process for each thread and
creates two helper processes, so an idle milter will look like this.

That's just an idle milter process.

I actually block a lot of spam via domainname and netblock blacklists
in access.txt, so I just commented those out to get more spam sent to
the milter.  I don't have a message that I know kills it or anything.
