Well, Franz Inc. being the provider of Allegro CL on the NeXT, I think
rather nice.  We've tried to take full advantage of Mach, where possible,
which itself is very nice.  For example, DUMPLISP creates a Mach-O file
which causes segments to be mapped to their proper address, without 
having to shuffle memory around after restarting the image.  Also, we use 
file mapping for foreign functions.  In the future, we hope to use Mach 
threads for Allegro CL multi-processing/stack groups.

Aside from these differences, Allegro CL 3.1 on the NeXT has the same
features that other versions of Allegro CL 3.1.
