This will pretty quickly result in toolkits, or at least app skeletons, doing
something like:
(void)max_unresponsive_time(MAX_DOUBLE);
I had an 'automatic wait cursor' feature in a window system I did, which when
an app failed to process pending events for a few seconds, would automatically
display a 'wait cursor', the dreaded Spinning Pizza of Death. Naturally, app
developers were insulted that the system would dare indicate that their app was
being unresponsive, and demanded such an API. Being the annoying curmudgeon
that I am, I refused to allow apps to feign being responsive when they really
weren't, as that wound up annoying users even more. (System cues shouldn't lie
to users.)
I did use the same mechanism to post notifications to subscribing apps when an
application became unresponsive. This allows an app that shows the status of
other apps, like the Unity launch bar, to listen for notifications of
unresponsive apps, specially badge unresponsive apps if desired, or offer a
'force quit' contextual menu item.
