Hi,

If I have two futures f1 and f2, can I compose them to a future that
completes with the result of f1 and f2 when both f1 and f2 have finished?
I'd like to have a future so that I can use the
then()<http://www.boost.org/doc/libs/1_55_0/doc/html/thread/synchronization.html#thread.synchronization.futures.reference.unique_future>method
to run another transformation.

I see method wait_for_all()<http://www.boost.org/doc/libs/1_55_0/doc/html/thread/synchronization.html#thread.synchronization.futures.reference.wait_for_all>but
this method blocks.

Best,
Kaspar
