Hi Vasily,

I tried myself porting sbcl to dragonfly, and succeeded insofar as I removed
some kernel panics caused by sbcl.

I cannot though reproduce your problem on my machine right now, can you ple=
ase
advise me about what version of dragonfly's world/kernel you are using and
which steps exactly i have to take to reproducethe problem?

Looking at threading problems in gdb is usually less than useful.

Cheers,
Markus
