Many of these are not bugs, but a few are tests not checking errors, and

* retry locks on network errors
When communicating with a local agent and watching a lock, a dropped
connection between the agent and server will show up as a server error
and immediately be retried. However if the client is connected to a
remote server, a dropped connection immediately aborts the lock.
* Updates comment about it being unsafe for writes.
Previously, it would try once "up to" the timeout, but in practice it would
just fall through. This modifies the behavior to block until the timeout has
been reached.
