Fixing PR port-i386/45946 (Kernel locks up in VMEM system)

[Matthias Scheler <tron%zhadum.org.uk@localhost>]

        Hello,

NetBSD-current has recently stopped working on my 3GB NetBSD virtual machine
because of the KMEM changes.

Lars Heidieker proposed the following change:

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.

        Kind regards
