I have been trying to integrate Dave Bailey's bsdproxy with an
experimental transport protocol (substitutes for TCP and preserves same
API semantics).  However, I can't seem to trigger a read event with the
new protocol-- the client side socket buffer fills up with data but
bsdproxy never gets a read event.  I have been able to use simpler
proxies (ones that basically pipe between descriptors) successfully.

Is there anything special that needs to be done at the transport layer
to trigger a kevent read?  My protocol calls sorwakeup() at the
appropriate times-- I had thought that would be enough and that kqueue
would be indifferent to the underlying transport protocol
implementation.  Nothing seems apparent in the TCP code, however.
