An issue that I'm seeing in some ITs.

For some reason, a number of tests seem to be failing due to an inability to connect to ZK
in a reasonable amount of time. I've seen ExamplesIT, DurabilityIT, ProxyDurabilityIT, and
SessionDurabilityIT all exhibit issues.

Not sure if there's something more heinous or if the timeout is just too low.
