One possibility: move to a multiple processes paradigm where each
buffer has an associated process, and global variable values are
propagated via message passing to a master process. Think Hoare's CSP
or Go or Erlang for precedents, though perhaps with more sugaring to
make it easy for Emacs users to not think much about global state.

This sort of model might be especially important if Emacs starts
being used as a serious web browser by lots of its community, given
how much CPU modern browsers can eat.
