Thank you for the explanation, Mehdi. About the "critical issues" mentioned
in the commits, as i understand:

[1] seems just socket timeout issue, and admins can adjust those kernel
params themselves.
[2] and [3] truly a problem about the heartbeat implementation, but it says
the fix is a part of py-amqp 1.4.0, and the dependency with kombu was not
[4] is a bug of kombu's autoretry method which is said to be fixed in kombu
3.0.0, it is not directly related to heartbeat.

Am I missing something else?
