Change looks good, is there any way to construct test case that reproduces issue?

[vlanse]

@jettify
added a test - it will hang forever without a patch, and it will pass with my changes
but had to use sleep() to enforce execution order on the loop

[jettify]

Can you please add loop=self.loop here? Looks like this is reason why on 3.4 test stuck.

[vlanse]

sure, thanks for pointing this out 👍

[jettify]

Thanks a lot!
