I don't think so, that is why I did not want to mask the bug. I think
we should put more DIAGNOSTIC stuff somewhere. Maybe the bug is in
checkalias() as you suggested? what happens if your nfs mounted partition
has device nodes? I guess you could not trigger the problem because
your nfs mount did not have devices?

# btw, use of VXLOCK in uvn_attach is abuse, isn't it?

Why? My understanding is that VXLOCK is asserted only when the vnode is
cleaned up?
