Description

Usually a permit acquisition is followed by an action, followed by a release of the permit. A simple enhancement to the existing Semaphore API can be made that enables asynchronous acquire:

<T> IgniteFuture<T> acquireAndExecute(Callable<T> action, int numPermits);

The method would immediately return a future to be later completed by the action's result. Permits are to be released after the future is completed.
