Unfortunately, the approach I tried, which was suggested by one of the 
MPS developers, fails badly.  I already mentioned the test failures, but 
now I've tried to run Emacs interactively, and I can't even get a 
directory listing.  For the record, I'm attaching the patches I've 
accumulated so far, but I'll have to try a completely different 
approach.  This will probably take me a while.

There are lots of test failures.  Back to the drawing board.
