possible concurrency bug causing lockup

[paralin]

Maybe related to #115

Had an issue developing starpc where sometimes (~10% of the time) the test would get stuck on recv() on both ends even after one side had sent the packet it was waiting for.

I was not able to figure out where the actual issue is located, but after I switched out mplex for yamux, the issue is gone.

So, I think the lockup issue must be in mplex somewhere.

Is there any reason you're using mplex instead of yamux?

Not using mplex anymore - switched to yamux. Just reporting the issue on mplex
