Port is not closed if the current thread is interrupted

[fwolter]

If the port is closed when the current Java thread is interrupted, the closing will be skipped silently.

IOLockedMutex.writeLock().tryLock() throws a InterruptedException here without even trying to acquire the lock. This skips the actual close without any notice.

Expected behavior would be to try at least one time to acquire the lock and close the port.
