NPAGES is size of attempted allocation or NIL for MDS requests.
Complications here because array space and MDS grow toward each other in two
separate areas: the first 8MB of vmem and the remaining 24MB.
Some machines cannot use the latter, so have to signal storage full when the
first fills up. Other machines have to know when to switch over.
Array space usually gets switched to the high segment before MDS, since MDS can
eat the lo space in small increments all the way to the end -
