It's the area I'd worry about first. A capability language probably 
shouldn't have anything one would think to call "global" variables, even 
with the scare quotes. I don't know what you mean by "dynamically-scoped 
variables", but if it's anything like Lisp1.5's or Smalltalk-72's 
dynamically-scoped variables, that'd be even worse.

Could you explain this one in some depth, at the lowest layer of abstraction 
that would be accessible to non-TCB code, so we can properly think about the 
limits of what such code might do? Thanks.

Unfortunately, I won't be able to get back to all this till probably Tuesday.
