Here is Gary's reply on openmcl-devel on how to set the initial or
`static' bindings of such variables rather than the thread-local
binding. Perhaps this is enough to obtain the desired behavior?

"If I understand the question correctly, the answer is that

(CCL::%SET-SYM-GLOBAL-VALUE sym value)

behaves like CL:SET, only it ignores any thread-local/dynamic
bindings of the variable and modifies the global/static binding.

The standard stream variables (*TERMINAL-IO*, etc.) are bound
in each thread (well, each thread that's created by the lisp);
the initial values of these bindings are the static values
of the variables.  So, setting the global/static value of
*TERMINAL-IO* would affect the value of *TERMINAL-IO* in any
subsequently-created threads."
