As a historical note, I argued against msgno during the standardization
phase, but I lost.  So, you're not the only one who finds it a bit
confusing. :)

(Although, it does leave the door open for a BEEP extention where you
could negotiate for an asynchronous channel, which would relax the
requirement that messages are replied to in the same order as they are
received.  That might be a better match for some protocols.)
