Hello,
Using sbcl 0.9.11 (+ threads) with slime from cvs duplicates output rather frequently.
Interestingly, this is a problem only on my single cpu machine (pentium III Mobile) and there it hapens very often. On the one with two cpus (amd64 x2), if it happens with slime from cvs and sbcl 0.9.11 with threads, it must be very rare; I haven't seen it yet.
Any ideas?
Regards, Mario.
