We have a sync without data written. It seems that in pageflush(), I
have UVM_OBJ_IS_CLEAN(&vp->v_uobj)

My test case iterate creating and deleting the same file. PUFFS assigns
it the same cookie on create after reclaim, which suggests the vnode is
being recycled. Is it possible it gets confused about the changes to
flush?
