That's only true if you use -q with a time. If you just use -q on its
own, it runs ONE queue runner process. That is
exim -q15m => start a queue runner now, and then every 15 minutes
exim -q => start a queue runner now (only)
In fact, in the second case, the command becomes the queue runner.

It is certainly a deliberate design, because the fewer synchronisations,
the less chance of bottlenecks.
