Remember those nasty problems regarding restarting lisp that we were having? No? Well, let me refresh your memory.

The symptoms were that a newly built lisp would die on startup, despite having been running safely for the previous 10 minutes or so compiling the Common Lisp Object System (which is marvellous, incidentally; maybe I'll chat about it another time). Anyway, this was only tickled by a bugfix patch of mine, so it got dropped.

Until this week, when I noticed a way to reproduce it trivially in our current builds. This elevated priority sufficiently for Dan to fix the symptoms. Phew.

But the really good news is that this fix has unblocked the bugfix patch that tickled the problem in the first place; which is nice, as it happens, because we had a user report the problem (again).
