I'm having a problem with understanding the difference (and applications) between private and system message pools. I see the difference between the private and system message queues (blocking vs. non-blocking receiving). I suppose that I can send a message to the private message queue only if the message comes from private message pool. And I can send a message to the system message queue only if the message comes from system message pool.
Am I right ?
If not - what's the difference ?
