Yes. The mini module is driven by a simple kernel timer, that is *not*
executed in realtime.

It has no default. If the --rtai-dir is unset, the RTAI example isn't
built. This option is only used for this example, the master itself does
not depend on RTAI or other realtime extensions. It can be executed in
any context.
