Wait timeout glitch for consumers with more than one queue

[doalex]

Consumers with more than one queue one of which is empty will usleep($this->waitTimeout). Which will lead to delayed processing of the other queues.
Ideally there should be a configuration with which it will be possible to configure the strategy of processing several queues (round-robin, fully-process-non-empty-queue). Do you think such a configuration would make sense?

Sorry for the slow feedback, I am sick at the moment. I'll try to provide a solution until Friday.

I have a prototype implementation ready, give me a day to test it.
However best performance can only be guaranteed, if we push this responsibility back to the amqp-extension. But unfortunately the consume() method is a blocking call and your system administrator does not like to install https://github.com/rstgroup/php-signal-handler

Please test this branch "wait_timeout_fix" and let me know.
