Symbol *default-special-bindings* is exported and documented, but it
does not appear to be implemented
max@momoland:~/lisp-systems/bordeaux-threads_0.5.0> grep -i default-special **/*
src/bordeaux-threads.lisp: #:*default-special-bindings* #:*supports-threads-p*
src/bordeaux-threads.lisp:(defvar *default-special-bindings* '()
Should not the make-thread function massage them and do (progv ...)?
