Yes, that's right.

It's certainly OK. Whether it's more efficient or not depends on exactly
what you're doing, but it is definitely more efficient in terms of
socket/TCP resource use. Bear in mind that all the channels are
multiplexed together onto a single TCP socket, and so one channel may
momentarily force another to wait.
