this is sbcl 1.0.18 with threads on mac os 10.5.4.
Do others see this too? On Linux with SBCL 1.0.4.15 and 1.0.18.debian everything works quietly.
I do see these messages, on the same setup as the original poster (sbcl w/ threads, OS X 10.5, Intel). However, they happen seldom for me, and mostly when I abort computations, or use restarts which throw me back to toplevel.
I did not investigate how to trigger the warnings reliably.
