bt:make-thread uses a funny table with custom bindings to initialize standardized globals like *print-readably*.
This seriously interferes with applications using Hunchentoot.
I have already posted to bordeaux-thread-devel stating that the new thread should probably inherit the values from the parent thread, but things are slow there I think.
FYI we now have this in Weblocks to work around at least the aforementioned variable (which causes the biggest problem because a lot of ~S format directives suddenly become trip mines):
(defmethod process-connection ((acceptor weblocks-acceptor) socket) (let ((*print-readably* nil)) (call-next-method)))
Hunchentoot should probably provide a similar workaround until the thing is sorted out on the BT side.
Other rebindings seem to be pretty harmless in comparison, but YMMV. :(

I'd rather not have that. I'd prefer to wait until Bordeaux Threads has sorted that out instead of adding a kludge. Until then, user code should take care of this itself.
Thanks for the info, though, I didn't know that.

Can you be more specific about this? I have not found any funny tables in my copy of bordeaux-threads, and I am also wondering why *print-readably* would be non-nil in the first place. Maybe the global value has been messed with?

It's a pretty recent change in BT. See src/bordeaux-threads.lisp:108*.
The table is there, I'll leave it to yourself to judge whether it's funny or not. ;)

I concur with Edi here: Please have the BT people fix that.
