Because "Processor yield" gives lower priorities a chance to run if the
highest-priority process is the sole in its class and yields; and so does
the round-robin that is enabled by --enable-preemption.

No, instead it only applies to --enable-preemption ("by default the system
is compiled with preemptive multitasking disabled").

It should be, but of course it is more prone to exhibit bugs and race
conditions.

Yes.
