In general, the current distributed lock is susceptible to time skew in config servers and mongos clients. This update uses an algorithm that checks for time skew, as well as providing some more robust tests to make sure a distributed lock cannot be forced prematurely. Some documentation on the website, currently hidden from non-10gen, gives more info.
