I've even got the source for one, just needs porting from SVR4
(not solaris).  Only trouble is it relies on vnode hold counts,
not vnode locks.

(Actually I'm not sure the readdir code for unionfs is actually right,
I had to go to much greater lengths to get it right in my fs.  All
to do with very big directories - the code has to be O(n^2) on the
number of layers in that case).
