Is this still true after it switched to using FuturesOrdered?

I see. Being single-threaded would just make it cheaper to synchronize / borrow the state mutably. So the root of the problem seems to be select? I'm looking forward to see how moro will help then :)

  High-level RTSP multimedia streaming library, in Rust (by scottlamb)

I suspected exactly that in this issue in one of my libraries, but when I actually looked with strace, I didn't see many syscalls returning EWOULDBLOCK. So then after that measurement, my new theory was that e.g. tokio::net::{Udp,Tcp}Socket would skip actually issuing the syscall if the mio layer hasn't returned availability since the last poll. Not true? Maybe I need to run my experiment again...
