             This rule checks if you're using <c>lock</c> on the current instance (<c>this</c>) or
             on a <c>Type</c>. This can cause
             problems because anyone can acquire a lock on the instance or type. And if another
             thread does acquire a lock then deadlocks become a very real possibility. The preferred way to
             handle this is to create a private <c>System.Object</c> instance field and <c>lock</c> that. This
             greatly reduces the scope of the code which may acquire the lock which makes it much easier
             to ensure that the locking is done correctly.
