Future: ported to Ephemeron + exception enhancing
A future always carries a fix_exn with it: a function that enriches
an exception with the state in which the error occurs and also a safe
state close to it where one could backtrack.
A future can be in two states: Ongoing or Finished.
The latter state is obtained by Future.join and after that the future
can be safely marshalled.
An Ongoing future can be marshalled, but its value is lost. This makes
it possible to send the environment to a slave process without
pre-processing it to drop all unfinished proofs (they are dropped
automatically in some sense).
