The test are flakey because many of them have to wait "for a bit" for
things to settle (session to fail, ephemeral to delete, etc.). But, the ZK
server has essentially random behavior in terms of when it reconnects,
connects, etc. If the VM is gc'ing or your system is slow, etc. it gets worse.
I keep trying to tune things but it's still not perfect.
