Sounds plausible.  As I said in my original post however, I'm using SBCL
with multithreading.  I've been looking in SBCL the manual, but I can't
find anything similar to setq-default.  As far as I know, setq is the
correct thing to use for new child threads to inherit the values of
special variables.  So apparently my setq is not being executed in the
"root thread"?
