With #41101, we handle the shutdown event. It would be good also to handle the logoff event. From https://docs.microsoft.com/en-us/windows/console/handlerroutine

When a console application is run as a service, it receives a modified default console control handler. This modified handler does not call ExitProcess when processing the CTRL_LOGOFF_EVENT and CTRL_SHUTDOWN_EVENT signals. This allows the service to continue running after the user logs off.

Since CTRL_LOGOFF_EVENT doesn't necessarily terminate a process, we should consider providing a cancelable API for logoff instead of ProcessExit.

Related is this discussion of a cancelable API for SIGTERM: #35990 (comment)

    I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

    @danmoseley I think we can close this one based on this fix, yes?

    The PosixSignalRegistration API does not handle CTRL_LOGOFF_EVENT that this issue is about.
