It can be very cumbersome tracking down references being bumped by
vref/VREF and other operations.

Among the uncompleted operations are VOPs that pre-release the returned
vpp to the caller. I think in VOP_MKNOD this was done as a convenience
and you might have to add code to handle device vp aliases correctly.

Just remember the rule, the allocating layer must be the layer that
deallocates.
