The crowning bugfix.

The problem was that with high load, circuit package window was
reaching 0. Whenever we got a circuit-level sendme, we were
reading a lot on each socket, but only writing out a bit. So we
would eventually reach eof. This would be noticed and acted on
even when there are still bytes sitting in the inbuf.
