If I say something like

	def [promise,resolver] := Ref.promise()
	alice <- resolve(resolver)
	bob <- resolve(resolver)

where alice and bob are in different remote vats, how is the race between
the two attempts to resolve the promise handled? I saw mention on the
erights site that it distinguishes local and cross-site promises, so I
guess that after the send to alice the reolver has changed, and that bob
gets a different kind of thing to alice. Perhaps the promise only ever has
one end that can be resolved at any time?

Tony.
