So -- what I'm getting from this is that:

1) The normal Lisp functions (like Fcons) can only be used in the main
thread, 

2) so we need a new list, pending_c_funcalls, which might perhaps not be
a Lisp thing at all, but would be (for instance) a chained struct
containing pointers to the callback Lisp_Object data, as well as a place
to stash C values and a mechanism to say what these C objects are, so
that they can be converted to Lisp_Objects, and

3) nobody has done anything like this in Emacs before?  :-)
