Re: Sql.FutureResult, an Sql.Connection Concurrent.Promise interface

[Martin Nilsson (Coppermist) @ Pike (-) developers forum]

Specifically for the case with multiple blocking dependencies I would
like to see an API like

  Concurrent.Promise all = Concurrent.Promise();

  all->depend( db->promise_query("SELECT foo") );
  all->depend( db->promise_query("SELECT bar") );

  all->then(do_ok, do_fail);
