... not every day do i get an opportunity to trace a bug from an application i was simply trying to use, all the way through hyper, tokio, mio, and std::net_imp into some deeper abyss what possessed the environment i'm running to return -ENOENT from getsockname()? i have no idea

instead i got (with the bind() call succeeding on strace): > thread 'tokio-runtime-worker' panicked at 'error binding to 0.0.0.0:8082: error creating server listener: File not found. (os error 2) which makes absolutely no sense however you may look at it

naturally, if i use `strace --trace=getsockname -Z` then the getsockname call succeeds. what the fuck

I don't think it's the issue here but one reason that could happen is that something else was using ptrace and causing the breakage, so having ptrace already attached stops is from causing the problem. Seen this before.
