> 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.
