No timeouts are specified in any requests

[blagh]

E.g., here - the request could hang indefinitely because no timeout is specified. Specifying something here would be great, but being able to configure that value with the rest of the client would be event better.

@blagh Fair point. We could expose the timeout config from requests via RestClient.
