Commit 4244875ddd74f41d67f4fca11166fc6d43bc4d93 in qpid-proton's branch refs/heads/master from [~aconway]
[ https://git-wip-us.apache.org/repos/asf?p=qpid-proton.git;h=4244875 ]

PROTON-825: BlockingReceiver.receive() uses 100% CPU.

Fixed in  BlockingConnection, by setting BlockingConnection's timeout on it's Container.

NOTE: Prior to this fix you can work around the problem as follows:

- self.connection = BlockingConnection(url, timeout=timeout)

+ container = proton.reactor.Container()
+ container.timeout = timeout
+ self.connection = BlockingConnection(url, timeout=timeout, container=container)

Timeout can be None to wait without limit until something is available.
