The test case below has a pub socket, a sub socket, a poller, and a queue to feed the pub socket. It creates the two sockets, adds them to the poller, and then calls RunAsync. A single message (17) is queued, retrieved from the queue by the pub's SendReady method, then received by the sub's ReceiveReady. Works great.
However, my use case is such that the sockets will come and go over the lifetime of the poller, so what I actually want is to call RunAsync and then add the sockets (as noted in code). But when I do that way, it seems that ReceiveReady is never triggered.
So either there's a bug in the poller, or (more likely) I'm doing something wrong... Does the call to Add need to happen inside the poller's thread maybe? I tried that -- using the poller's Run(Action) method -- but it didn't seem to work.
Actual behaviour
The code below, as written, passes cleanly.
Steps to reproduce the behaviour
Comment out the line poller.RunAsync(); and uncomment the line /* poller.RunAsync(); */. The test will now hang.

poller.Add(pub);
var sub = new SubscriberSocket(port);
sub.Subscribe("");
