The idea is that this kind of process WANTS to be a CPU hog. If it were
not for the fact that the I/O is not immediately available, it would
never want to sleep. The only thing it ever blocks on is the read, and
this is involuntary. It doesn't use a non blocking call because it
can't continue without the data.
The questions is: Does this matter for the issue of interactivity?
