Re: Loading slime 2.27 going into debugger as of last night.

Another piece of information. I have a more or less identical production server which isn't having
this problem. But I haven't run dist-upgrade on it recently. The latest version of slime it has is
v2.26.1. It's running sbcl 2.2.1.

The system giving me trouble is v2.27 slime and 2.2.2 sbcl.
