Subject: Bug in notes regarding rps_rcvclose()

(This message is being sent to all CPSC 360 students)

The notes on page 42 of rps.pdf INCORRECTLY stated that
rpsock->state should be set to RPS_SHUTDOWN AFTER the
rpsock structure has been freed.  Needless to say, changing
an element of a data structure that has ALREADY BEEN FREED
is BAD TO THE BONE.

The state change should occur JUST AFTER the receive
ring has been drained.

I think I have fixed the notes now.

Thanks to Ms. Feaster for pointing this out.
