I find it much easier to go through and verify that (for instance) all
the VOP_ISLOCKED changes were done correctly in one pass if you don't
have to wade through other changes while doing so.

I'd realy prefer to see this part of the change backed out as
completely unrelated to the UBC/UVM tweaks.  How much performance gain
do you get *specifically* from nuking v_lease?
