This should be fixed with commit 088621c17af05faef491565f0d1b276d7b2077d0. The panic was actually rooted in the polling framework not playing nicely with kqfilters on ttys. SBCL opens /dev/tty and uses it only in it's debugger which is why the problem only occurred after sbcl had dropped into the debugger.
