737a20b8fa Fixes for distributed lock handling time skew. 
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.
