Well, it does look like that's the "real" initial thread, which basically
(dolist (stream list-of-streams-to-automatically-force-output-on)
and it (not too robustly) got an error trying to do a FORCE-OUTPUT
on a closed TCP stream. (Checking for a closed stream and removing
it from the list seems like it'd be a better idea.)
If you still have that lisp running, could you drop into the kernel
and send me the output from its backtrace command ?
