Looking at the code is seems to be for a reimplementation of
__access_remote_vm. So at very least it should use that, but I still
requiestion why it's doing that at all.

Geert, please don't just export stuff for staging/ use only. Code
wouldn't be in staging if it weren't a steaming pile of junk, so
adjusting anyting in the real tree for it needs proper discussion first.
