[PATCH] Use std::async instead of our own parallel execution instrumentation.

[Rui Ueyama]

I don't understand why you think platform specific frameworks would work
better than the C++11 threading library. There should be no fundamental
reason the C++11 threading library is less performant than
platform-specific ones. Or, are you talking about some platform's
implementation of the C++11 threading library is currently broken?
