You may be right about CMU-CL, but I'm not crazy about starting this
with a CL we don't have source for.  Also, if we are going to have to
add threads to CMU-CL (or whatever we choose), we might as well started
doing this at the beginning.

This can proceed in parallel with the other work, but should be
started at the beginning.
