Hello all;

This change fixes an issue with the instance returned by Collections.synchronizedNavigableSet().tailSet(Object,boolean) which synchronizes on wrong object, itself rather than the same mutex as it's source.

Since I was concerned that there might be other lurking errors I opted to create a fairly thorough new test which, thankfully, revealed no additional problems.
