You may be right. Thanks for the explanation. I think Peter Conrad can better explain what he actually meant.

What I got form this confusing sentence, is that Peter conrad has actually succeeded in breaking the lock bits. Thats why I asked him to share with us so that we may be able to use some more secure protection scheme.

If this is the case then Peter Conrad probabily missed a "coma" at an appropriate place and I should apologise with him for anything wrong from my side.
