It looks like you've done a good job.

    4) Adding an option to configure.in to enable a (default=off) switch for
       USE_XCACHE.  I don't feel like learning autoconf for this one thing.

Such a feature would be a bad idea--useless complexity.
Using a configure option to control something is a last resort.

What would be both simpler and more useful is a feature at run time to
turn the cache use on and off.  A Lisp variable forwarded with
DEFVAR_BOOL to a C int variable could control it.  The entry points
could avoid checking the cache if the C variable is 0.
