rmind says the problem is that tvp (aka tochild_vnode) comes in locked
if it's not null, and I misread vnode_if.src and thought it wasn't.

So unlocking that up top should solve this problem. (I thought I'd
tested this case but apparently I didn't.)

I got an extra pile of crap dumped on me and consequently don't have
time to look at it in any detail for the rest of the week. :(
