Yes, that's exactly the problem. It is nothing specific to your particular
library but a general issue to solve. In the library we develop (HPX,
https://github.com/STEllAR-GROUP/hpx/) we face the same issue of having to
rely on our own synchronization primitives which makes it impossible to
reuse std::future (or boost::future). Any suggestion on how to create
specialization/customization points allowing to make boost::future
universally applicable would be most appreciated.
