I don't know. But the low-levelness contributed by async_call is unique, and
not covered by boost::thread at present. I'm thinking of the R f() -> { void
f(), R result() } transformation, with the associated synchronization and
(possibly) encapsulated exception transporting/translation from the
execution to result(). It's a tool that allows high-level interfaces to be
built. Whether people will want/need to build their own high-level
interfaces is another story.
