Right now when kwin exits, the user is taken directly back to the login screen. The login session exits, so all processes then are killed by the session. This patchset introduces a mechanism to safely restart kwin. The socket (typically wayland-0) remains alive and persistent across restarts. This means if any process reconnects through it's own mechanism or a crash restart handler the socket appears to work, and blocks until the new kwin restarts. This makes it secure and race free. If the screen was locked at the time kwin went down, this is also secure. Kwin now checks the status from logind at the time of launch, so will immediately restore a locked state before any other rendering.
