[Kittyhawk] KH is not fault-tolerant/fault oblivious

Okay, to start out with, I'd like to say I triggered this by doing
something I shouldn't have been doing -- but regardless, it crashes
the khctl node -- the memory buffer console turned out to be
unnecessary, it dumps out quite well to the jtag console (which is
lucky because I didn't boot my new kernel on the khctl node).

I'm still working on stable reproduction, when I have it I'll pass it
on -- but offhand I think we have a memory leak in the tree receive
path.
