History
Poul-Henning Kamp 851a87ea1a Vnodes pull in 800-900 bytes these days, all things counted, so we need 
to treat desiredvnodes much more like a limit than as a vague concept.

On a 2GB RAM machine where desired vnodes is 130k, we run out of
kmem_map space when we hit about 190k vnodes.

If we wake up the vnode washer in getnewvnode(), sleep until it is done,
so that it has a chance to offer us a washed vnode.  If we don't sleep
here we'll just race ahead and allocate yet a vnode which will never
get freed.

In the vnodewasher, instead of doing 10 vnodes per mountpoint per
rotation, do 10% of the vnodes distributed evenly across the
mountpoints.
