Ok, that's coming from the thread struct:

(let () (list *state* *no-tls-value-marker* *os-thread* *pseudo-atomic-bits*))
=>
(1 #<unknown immediate object, lowtag=#b1, widetag=#x61 {61}> 70368646560640 0)

due to sb-vm::symbol-thread-struct-offset disregarding the package.

But I'm not quite sure about the whole meaning of treating thread slots
in such a way.
