What would be an acceptable upper limit? 256MB? 128MB? The test
I ran (Kirk's news test) ate around 60MB for the "FFS Node" memory area
before the number of vnodes stabilized, on a 1GB machine. I would say
that a 128MB upper limit would be too small for a 4G machine. A 256MB
limit ought to work for a 4G machine
Since most of those news files were small, I think Kirk's news test code
is pretty much the worse case scenario as far as vnode allocation goes.
