An update: Although the above resulted in the server accepting
new posts again, it was still running an excessively high load.
The problem appears to have stemmed from someone in Toronto, Canada
running a script which was making (and still even now is trying to
make) multiple simultaneous, aggressive, CPU-intensive NNTP connections.
Anytime I killed one of these connections, a new one started up
instantly. Consequently, I have blocked the offending IP address and
it is no longer able to make NNTP connections. I apoligize for any
outage you experience because of this.
