About fork oslo.messaging transport object

oslo.messaging can't ensure that forking a process that shares the same transport object is safe for the library consumer, because it relies on different 3rd party libraries that don't ensure that too, but in certain case/driver it works:

  • rabbit: works only if no connection have already been established.
  • qpid: doesn't work (qpid library have a global state that use fd that can't be resetted)
  • amqp1: works
