Thank you for filing this PR, could you rebase on the latest changes in master now that #106, and do you think it is possible to test this?

I tested on my test server and now works on the production server

@viras777 Thanks for the update. Any clue what it fails for certain jobs?

In the function awaitConnectionTune I added interception of all exceptions to be able to process in reject.
like this:
Connection = (new Client())->connect()->then()->otherwise();

Because of this, the tests do not pass, they expect another type of exception

Sometimes there are missed hearbeats with an error on the rabbitmq server: "missing heartbeats from client, timeout: 60s" and bunny take 100 CPU for a while.
This happens when $nextStreamSelectTimeout < $ now < $ stopTime
For example call method run(1) and wait 60s
