Pinned in the AIX-style "pinned memory" sense?  Succinctly, AIX
allows userland programs to tag memory pages so as to guarantee that
they will not be swapped to backing store.  Portions of the _KERNEL_
are paged out instead if necessary.

I assume that the pinning is of the AIX sort and that it is desirable, if
not necessary, for the realtime throughput guarantee policy.  Nes pas?
