[Vortex] General Vortex Library / BEEP concept questions

Just to clarify that the limitation is about the order in which replies
are sent. In the particular case of Vortex, you can send any number of
messages without waiting to be replied (without taking into
consideration if there are pending replies to be received).

Once they are received and replied by the remote peer, they will be
received in the same order as established by messages sent.

Right. In the case you want to have an ensured reply to your message
without being blocked by previous pending transactions you can do so. 

A function that could help to check if a channel won't block the caller
by pending replies is vortex_channel_is_ready.

Cheers!
