Fixing PR port-i386/45946 (Kernel locks up in VMEM system)
NetBSD-current has recently stopped working on my 3GB NetBSD virtual machine
because of the KMEM changes.
Lars Heidieker proposed the following change:
RCS file: /cvsroot/src/sys/arch/i386/include/param.h,v
retrieving revision 1.75
diff -u -r1.75 param.h

And this change fixes all the problems I have observed.
Is there any reason not to commit that? I'm particular wondering what
influence the patch will have on machines with low amounts of memory.
