There is no excuse for that.  They have nothing whatsoever to do with each
other.  The proxy object changes should be in vm/ and I can't see why they
shouldn't work back-ported to 1.x (not that we care to do it).  There are
IKOT_* values already unused and it's easy enough to add another anyway.
The ipc glue code you need is trivially copied from the other ones.
