Do you have the http_proxy environment variable set in the shell from
which you (re)start FilterProxy?  FilterProxy obeys this variable, and
would use itself as the upstream proxy!  This can (and should!) cause a
fork-bomb.

Perhaps this would be a case worth detecting...and refusing to use
itself as the upstream proxy.

Thanks for the digging on LWP too.
