Comment:

	Make context opaque
	Make flatten/unflatten for it
	Add attribute to contexts (at creation)
		intra-communicator only (default)
		inter-communication OK

This adds to safety, allows one to hide the dual context nature in
communicators, and should allay concerns of Jim Cownie about unsafe
contexts.  It euphemizes implementations, so there would be much
more freedom in implementation, with the opaque context.

This upsets Sandians, because it limits ability to access contexts
like well-known ports.

What do you think?  Does it help with inter-communication?
