Per discussion with Clint at the platform rally, we believe this is likely due
to a problematic buildd environment, that's resulting in a resource constrainment
that's causing issues for the zookeeper server. The test suite is showing
several cascading timeouts, but this hasn't been observed anywhere else outside
of a small percentage buildd servers. The overall size of data in zk for any
given test run is very small (on the order of a few mb) and is cleared out per test.
