Jordan Zimmerman commented on CURATOR-233:
------------------------------------------

I'm going to try to take over this task as [~mdrob] is MIA. Can the test you attached be converted
to a unit test? It would be far easier to see and maintain the issue.

> Hi,
> I think I discovered a bug in the internalLeave method of the double barrier implementation.
> When a client is told to leave the barrier after maxWait it does not do so. A flag is
set but the client does not leave the barrier, instead it keeps iterating through the control
loop and drives CPU usage to 100%.
> I have attached an example.
> Best regards
> Lianro
