Description

In order to support non-blocking use cases and be more in-line with Java's Semaphore class, TimedSemaphore should support a tryAcquire() method:

public boolean tryAcquire();

The method checks whether another permit can be acquired. If so, it acquires the permit and returns true. Otherwise, it returns false without blocking the calling thread.
