Unfortunately there is (to my mind at least) one core problem which muddies
the waters of how a universal FFI for Scheme implementations - the fact that
there is not an obvious 'right' way to implement
CALL-WITH-CURRENT-CONTINUATION, which has deep implications for the way that
the stack gets used.

Most of the rest of the issues in an FFI do not have much variance between
implementations and you can isolate them behind COND-EXPAND fairly easily.
