Yes, that's the right track...

DOH!  That's it... I didn't think to check the package as I hadn't  
explicitly switched to anything other than CL-USER.  Apparently,  
something (SLIME or my setup code) is dropping non-repl threads into  
other packages.  Should be easy enough to track down now that I know  
what I'm looking for.
