[slime-devel] problem with slime from cvs head and sbcl 1.0.23

I am seeing a problem with the cvs head and sbcl 1.0.23 - slime does not clear the window and present me with the repl prompt. Instead I see the *inferior-lisp* window. Here is the last bit that shows up:

; loading #P"/home/ramb/.slime/fasl/2008-12-25/sbcl-1.0.23-linux-x86/swank.fasl" WARNING: These Swank interfaces are unimplemented: (ALL-THREADS CALLS-WHO DISASSEMBLE-FRAME INTERRUPT-THREAD RECEIVE-IF SEND SLDB-BREAK-AT-START SLDB-BREAK-ON-RETURN SPAWN WHO-SPECIALIZES) ;; Swank started at port: 46259. 46259 *

slime asks me about a version difference, I answer 'y' and then slime thinks that everything is OK. But the repl promt never shows up.

Any suggestions on how I can debug this?
