There is a problem with MacTCP.lisp on newer machines which I haven't
fully investigated, but for which the workaround is to turn off the ASYNC
bit in the #_Control trap in the TCP-CONTROL function. In my case a IIfx
which simply inherited a newer ethernet board would intermittently hang
or crash when using TCP from MCL (but not from other applications). See
if this helps. Let me know if it does, I'll try to push up the priority of
investigating what's really going wrong...

Well, there's a set of patches that was a candidate for being released, but
I discovered that the MCL system wouldn't correctly compile itself with
all the patches loaded and haven't yet had the time to identify and either
withdraw or fix the culprit(s). When I do, we'll release that set.
Since that set was put together, of course, both Bill and I have been
accumulating more patches as bugs get reported and fixed. Unfortunately,
creating a patch to fix a single case that a customer reported is different
from ensuring that it works in all possible cases and therefore is worthy of
widespread release (as the experience with the last set which we THOUGHT
was ready for release shows), so I'm hesitant to publicize the list.
However, if you have a bug that's bothering you (or even suspect a possible
bug in some area), by all means send mail asking about it.
