100% CPU usage on idle

[tsurai]

Hi,

I'm having a problem with the zmq sockets causing a very high load.
All of the Zmq sockets idle at 100% CPU per thread once the first future has started despite not having any load on it whatsoever. My project ends up causes a huge CPU load since I'm using several sockets at once and they all cause a thread to idle at max CPU speed rendering the whole system unusuable.
Is there any way this could be fixed?

can you provide which version of tokio-zmq you're using, and a minimal example that exhibits this behavior?

I'm using version 0.10.1 as stated on crates.io but can also replicate it on the current sources in the development branch.

I can reproduce it by taking the dealer_router example code and remove the controlled() calls on the dealer and router stream of the broker to keep them open. Running the example like this causes a thread to idle on 100% cpu after all messages were processed.

Thanks a lot for looking into this
