> For Java7+, try-with-resources makes using locks safer. Curator should have a utility
for this. Something like:
> {code}
> public class SafeLock implements AutoCloseable {
>   private final InterProcessLock lock;
>   private final boolean acquired;
>   public SafeLock(InterProcessLock lock, long timeout, TimeUnit unit) {
>         this.lock = lock;
>         acquired = lock.acquire(timeout, unit);
>   }
>   public void close() throws Exception {
>       if ( acquired ) {
>            lock.release();
>       }
>    }
> }
> {code}
