Sorry for possibly getting back to a dead horse, but what if we set
c->keepalive to AP_CONN_CLOSE and sent an EOS bucket?
Of course currently this would only cause the connection to the client =
to be closed.
For the notification of the filters on the stack that something has gone
wrong we need additional measures as the error code addition to the
EOS bucket.
