Criterion hangs the process because for some reason the server socket can’t detect that client has closed connection

[softstream-link]

This only happens on Linux but works fine on Darwin and when criterion is used to do clt.read , however when a standard for loop is used all works fine

• Example contains a main function which in-turn calls two for the most part identical functions

let _ = clt2svc_without_criterion();
let _ = clt2svc_with_criterion();

• Both functions have the same objective

• create and connect two non-blocking TcpStream’s to each other

  • clt TcpStream, will connect from main thread
  • svc TcpStream, will be accepted from Svc-Thread thread

• svc TcpSteam will continually write to the socket untill it gets an io::std::Error

• clt TcpStream will continually read N number of times and then issue clt.shutdown(Shutdown::Both)

• The only difference between two functions is one uses criterion to measure the read speed and the other a standard for loop. However the one that uses criterion variant hangs as the svc TcpStrem gets ErrorKind::WouldBlock instead of ErrorKind::BrokenPipe
