Would it not make sense and be useful to have an uninterruptible version of
acquire on Semaphore? This method could be used in cases where you are using a

This way the application would not need to throw InterruptedException from all
the methods that acquire the Semaphore permit. Alternatively if the exception is
not propagated then the application would not have to catch the
InterruptedException and then re-attempt to acquire the permit and then set the
interrupted flag. This logic could be hidden in an acquireUninterruptibly method.
It could also parallel the Lock protocol where there are both lock and
