This would be a bug (or shortcoming) in the OS: the application never
has to "relinquish the CPU" because the OS preempts the
application instead. But it's surprisingly difficult for an OS to make
sure that it's *always* responsive no matter what the applications do.
My guess is that Emacs started to eat up memory, causing the machine to
thrash, which is the typical situation where the OS becomes unresponsive.

Emacs does listen. You've hit some bug somewhere.
