Distinguish between EINTR and EAGAIN

[EugeniuZ]

Looking at this code: https://github.com/celery/py-amqp/blob/master/amqp/transport.py#L364-L366 I understand that socket.timeout() would be raised in 2 cases:

• drain_events() method is called with some timeout value and no message was received by the consumer in that timeframe
• process got SIGINT and the recv call was interrupted

Wouldn't it be better if client code can distinguish between the 2 scenarios ?

what better approach are you suggesting?

How about raising socket.timeout() for EAGAIN and re-raise socket.error for EINTR ?
