NMBCLUSTERS *is* the ceiling.  No memory is actually allocated
(although virtual address space is) until those clusters are actually
requested.

That would be an improvement, but recall that many of these sorts of
parameters are there in order to limit fragmentation of the kernel
virtual address space.  There's no safe way to GC kernel virtual
space.
