I may have not been paying close enough attention, but why is all of
this symbol value per thread stuff needed?
I suppose this is the way all other MT implementations do it?
I'm trying to figure out what's wrong with just rebinding a symbol in
a thread if that's what you want.

The previous msg said
  The whole point for this change is to be able to distinguish when
  special variable does not have binding (in thread) and when it was
  bound but makunbound-ed later (I came to this issue when adding clisp
  support to portable-threads).
But why should you want/need/be able to distinguish these two states?
