I am developing a small network of devices over Qnet, with one master and several slaves.
The master creates a channel with name_attach, and then creates a pool of threads reading from this channel id, and then
 the slaves connect to it with name_open.

The problem is, the sequence in which the devices are powered is not always consistent, and I seem to have trouble when 
two slaves are calling a name_open pretty much at the same time (might be that the connection requests are served "
simultaneously" by multiple threads unblocking in the master's thread pool).

So the questions:
Is there any kind of synchronisation that works through the network before actually establishing a connection (some sort
 of barrier or signal)? So I could keep the slaves waiting for the master to come alive.
Also, how shall I handle in the master's side the connection requests from the slaves coming with a name_open, so it 
supports possible "simultaneous" calls being served by a thread pool in an SMP?

If anyone can give me some insights, I'm already very thankful.
