Stack from ghstack (oldest at bottom):

Without this, we cannot guarantee that the various world/proc names are unique.

This was not a problem before D79478197 because each mesh was private -- the underlying agents were not wired together.

However, since the mock MAST allocator uses the LocalAllocator to allocate host-local procs, they are now all wired together, and messages, and subsequently, we have overlapping routing entries.
