> Here's a patch which adds a little WriteLock helper class for performing leader elections or creating exclusive locks in some directory znode. Note its an early cut; am sure we can improve it over time. The aim is to avoid folks having to use the low level ZK stuff but provide a simpler high level abstraction.
