'Leak' of channels (IModel instances) in case where connection is blocked

[michaelklishin]

In the Java client, the behavior of a Connection#createChannel call is not to return unless a channel.open-ok frame is received. When the connection is blocked by a resource alarm, that will not happen until the operation times out or the alarm clears. So I guess that avoids the leak.

In Bunny, in addition to the behavior above, there's a predicate on Bunny::Connection that returns true when the connection is blocked.

If the Java client option would be too difficult or impractical to pull off, the Bunny solution plus throwing an exception might be a good enough approximation.

I was the original author of the discussion post. I did try this again recently and the behaviour still seems to be there.

Thanks @michaelklishin. I moved this to an issue to try to reproduce it.
