Something in the changes on the 6th cause slime to freak out on sbcl 1.0.18 w/ threads on OS X. (This is sbcl from macports, if it might make a difference.)
cvs update -D '2008-08-06 17:50:37'
is the earliest change that reproduces the problem. (The preceding changeset won't start at all; changesets before that work fine.)
The symptom is a never-ending chain of these warnings:
WARNING: Releasing #S(SB-THREAD:MUTEX :NAME NIL :%OWNER NIL :LUTEX #<unknown pointer object, widetag=#x5E {11D7111F}>), owned by another thread: NIL
I haven't tried to track down the problem, yet. Does anything seem obvious to those responsible for the relevant changes?
Thanks, Thom
