It depends which O(1) scheduler you are using, there are multiple
variants.  In the version that SGI use on the Altix boxes, init_tasks
still exists.

However this has got to be enough of a nuisance that the next version
of kdb will drop init_tasks and use its own data areas to track the
idle tasks.
