On one hand I don't think that should be an application wide decision -
- an application may run threads of different priority -- and on the
other hand I still think that threads of little importance can be
identified by their priority, which would be <= B_LOW_PRIORITY. As the
registrar's updater thread would have B_LOW_PRIORITY it is even
guaranteed that the low priority threads won't be starved by the
updater thread.
