DefaultCacheManager.getCache() is still blocking until the joiner receives
some state (i.e. owns at least one segment in the consistent hash).

The pre-existing nodes are not blocked during this state transfer, and in
fact we didn't block the joiner either at the beginning but I re-added the
wait to fix some tests "the easy way". I created a task in JIRA to
re-enable this, although I'm not sure if it should be the default:
