Can you reproduce it with something other than SBCL? It's known that SBCL's dispatch caches are deadlock prone.

No, and I can say that because the first time I encountered this error was a couple of years ago, and I've also been using ccl without problems since then.

This is an example of the kind of deadlock I was referring to a while ago when I said that the flushing timeout was there for a reason.
The deadlock is this:
Compiler thread tries to output a compiler note. Holds world lock, wants the slime's stream lock.
Auto flush thread tries to compile a dispatch function. Holds the slime's stream lock, wants world lock.
...not saying that SBCL is behaving well here, but the deadlock is due to interaction with slime's stream lock and the auto-flusher -- and was fixed earlier.

I've committed a new workaround for these deadlocks to Slime -- this time touching code only in swank-sbcl.lisp, so hopefully it can stay in this time. :)
The root cause in SBCL is due to be fixed soonish as well, but even if that happened yesterday it would still be a pity if decently new SBCL's could not be reliably used with slime-repl from CVS HEAD.
