I agree; user interaction is effectively I/O on, usually, some sort of
event queue that collects from a variety of sources; with the
specialty that, in some GUI environments, the process's first thread
is somehow "special". But ultimately it's still a "worker thread" /
"interaction thread" model, which is quite a good one. The interaction
thread spends most of its time waiting for the user, maybe waiting for
STDIN, maybe waiting for a GUI event, maybe waiting on some I/O device
(TCP socket comes to mind).
