This is old, but I don't think I ever reported it to
scsh-bugs.

receive-message! usually returns a single value, the
number of bytes
read from a socket. According to the manual, it's
supposed to return
two values: the number of bytes and the remote
address. It does
return the two values when it gets EOF on the socket.

It's this line in generic-receive-message! that
returns the single value:

(if (>= i end) (- i start)

A consequence of this bug is that receive-message
usually fails since
it calls "receive-message!" and expects to get two
values.
