Hi,

  Onc of the design choices for async() default launch policy was to allow
the OS scheduler to decide whether or not to launch a new thread or remain
on the same thread (presumably based on available system resources).
Does Boost 1.56 or 1.57 support this default auto scheduling yet?
It seems to be launching as many threads as tasks.

Thanks,
Adi
