Of course, this is not true...
A process will still yield when waiting for a message, and might also
yield when entering a wait state (e.g. fetching from memory.)
This doesn't exactly amount to _even_ scheduling. However, preempting
processes based on CPU cycles rather than reductions (function calls)
seems more predictable.
