james strachan updated ZOOKEEPER-78:

    Attachment: patch_with_including_Benjamin's_fix.patch

this modified patch includes an implementation of Benjamin's algorithm, using 
w-sessionId-sequenceNumber as a naming convention so that we can reuse files 
created for the same session if we get a connection failure.

this patch also includes a unit test which tests out the WriteLock still 
working if we stop and start the server.

also the code is refactored so that all the retry logic is in ProtocolSupport

> added a high level protocol/feature - for easy Leader Election or exclusive 
> Write Lock creation

> 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.
