Yes, delete-frame has special code to deal with this.  I agree it's a
kludge.

I must clarify that there are no frame-local Emacs lisp bindings for the
environment, just frame parameters.  But otherwise you're right.

A cleaner solution would be to make server.el's client parameters (the
variable `server-clients') available to callproc.c, and use them directly.

People don't like the concept of client-local environments in general,
so I think it would be best to choose some other way to handle
environments instead.
