Browser? I'm not talking about browsers, I'm talking about every other kind of application that tries to use a userland protocol, because that seems to be the direction network libraries are aiming to go. I have no idea how to tell most (all?) debuggers not to halt particular threads, but it sounds painful. And my point is, there are consequences like this that no one seems to care about at all, but that I would hope would've been addressed before seeing people jump on the ship.
