We had a bug where an accepted socket would appear to be EOF/disconnected
on the accepting side until the connecting side had called attach_fd().
Fix this by adding a new SocketRole::Connecting state.
Track how many fds are open for a socket's Accepted and Connected roles.
This allows fork() to clone a socket fd without a subsequent close() walking
all over the parent process's fd.
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)
This is really cool! :^)
Apps currently refuse to start if the WindowServer isn't listening on the
socket in /wsportal. This makes sense, but I guess it would also be nice
to have some sort of "wait for server on startup" mode.
This has performance issues, and I'll work on those, but this stuff seems
to actually work and I'm very happy with that.
