This just occurred to me. Would it be possible to have current point
to a location within the kernel area that was mapped individually for
each task?
There are severe performance penalties for this technique on SMP, and
to a lesser extent on uniprocessors as well. This method is old hat
and was investigated by us a year or two ago, it was found to be
inferior to the current scheme.
