OK :)
Benchmarking message queues against pipes would be
interesting, maybe
Jack could benefit if they're faster?
I did some benchmarking between unix (local) sockets and message queues
and found speed (roundtrip) to be over twice as fast when using message
queues.
In test, process A sends message "Yoohoo" to process B and process B
replies "2U2" back. This is counted as a message exchange in the result.
On my P4/3000 I get this kind of number:
105193.5 messages / second
Nice feature of message queues is that you can get signal-style delivery
using mq_notify(3).
