Wierd Science, indeed.  We had been having problems with unix
connections in Lyric just hanging after a while, and discovered that
we didn't have the problem if FTPDEBUG was turned on. It's now our
default setting, and probably explains why I've never seen the bug you
mentioned.  The best explanation I could come up with for our problem
was that it was some sort of wierd timing bug, and the extra time it
took to write out the stuff to the debug window took care of it.
Breaking out the Lanalyzer didn't throw any light on it either. 

...arun

ps.  Isn't it fun trying to debug a problem which doesn't show up when
the debugger switches are turned on :-)?

pps.  I'm slowing building up a collection of patches to the TCP
system, so if any of you out there have any others, let me know.  I
currently have: The patches from lispusers on sumex, our patches to
make TCP domain work, and a couple of patches from England. We might
have to make a <lispusers.TCP> directory...
