Believed fixed:

        * ramap.c (raeql_1): Do not call scm_uniform_vector_length on
        arrays.  The length of array is already determined differently and
        scm_uniform_vector_length does not work on arrays.

Efficiency?  I don't know.  It's certainly a lot of hairy code.  Let's
not touch it ever again.
