NKMEMPAGES_MAX defaults to 1536 (6M) on NetBSD/sparc. On a
	reasonably heavily loaded 256MB sparc5 NFS/shell server
	under 1.6.x or 1.6ZK this very quickly leads to:

	    "panic: malloc: out of space in kmem_map"

	A similarly loaded dual proc ss20 running as an NFS client has
	no trouble.

	With NKMEMPAGES_MAX set to 5120 (20MB), there are no problems.

	I know sun4c machines have quite tight VM limits, but would it
	be reasonable to at least increase this to 2048 or maybe 3072?
