@htuch Do you think this is reasonable? |

@silentdai seems like an interesting optimization. Assigning to @eziskind for a first review, since he has been spending some time recently reasoning about the GC behavior of this code. |

Description:
The shared_ptr and the atomic<unit64_t> is duplicate in term of ref count.

cbandall_threads_complete_cbcopy at O(number of worker) scale.Theoretically the callback is passing by reference (was value copy) but I doubt anyone would rely on the previous behavior.
