I don't use cleanfeed itself, but I do use some cut'n'pasted bits of 
cleanfeed's anti-binary filtering.

After the third "jam" today, I went into my filters and commented/cut out
all bits of perl that dealt with __BODY__, including the cleanfeed parts.

The article I mentioned above was just seen and rejected in a perfectly
normal manner (unwanted newsgroup).

Also, when I attached gdb to the running (and spinning) innd process, I 
noticed that the regmatch() calls were operating on the body of the message.

So, I suspect that there is some kind of killer article out there that is
driving the INN perl filters wacky.  Unfortunately, I don't have the bodies
or header.  I'm using perl 5.004_04 linked into INN 2.3.0.
