Friends

Name	Description
operator!=	Compare two executors for inequality.
operator==	Compare two executors for equality.

The system executor represents an execution context where functions are permitted to run on arbitrary threads. When the blocking.never property is established, the system executor will schedule the function to run on an unspecified system thread pool. When either blocking.possibly or blocking.always is established, the executor invokes the function immediately.
