i looked in my copy of MacTCP.lisp, and only found two instance of the
#_Control trap being called (in %tcp-control and tcp-active-open). since
the one in %tcp-control was the only one that mentioned async, i changed
the following line in that function:
(when (eql (setq err (#_control :async pb)) 0)
(when (eql (setq err (#_control pb)) 0)
is that what you meant?
so i made a new version of our application with this change, and have sent
it off to the two people having this problem, and i'll soon know whether
this fixes our problem, or not. thanks a ton!

actually, i wasn't talking about the above problem at all. on various
occasions, i've seen bill say something about 'send mail and ask for the
make-lisp-faster patch' and i was just curious about that. i wanted to get
a list of those patches (and short descriptions of each) and to find out
how to get this information. is there a listserv? i looked at the cambridge
ftp site, but didn't find much, and i'm pretty sure that i've seen bill
announce more fixes than were available there. sorry i wasn't too clear...
thanks again! i'll let you know if your fix solves our problems!
