SmartDispatchQueue

public class SmartDispatchQueue : Equatable

A dispatch queue that will call a sync block inline if it can tell we are already on that queue, avoiding the problem of having to know if you are on that queue already before calling sync().

It also supports synchronous execution of the block if on the correct queue already, or flipping that to async if we are not on this queue.

Note

This is not safe to use when using Dispatch Queues that use a target queue. The block will execute on the target queue, and getSpecific will not return the correct value
