Note, though, that there are some handy features of non-LISP operating 
systems that we would probably like to have (certainly, that I would 
like to have).

One of them that I would certainly like to have is some sort of support 
for security; Symbolics and other LispM systems were quite insecure, by 
design. Anyone could frob anything in any process anywhere at any time, 
which was certainly very handy when developing software, but it's not 
so great when you want to have a system that lives on the net or 
otherwise shares resources with users and processes that may not 
necessarily be trustworthy.
