There is a hack based on device and inode numbers, but it is just a
hack.

The IPC that wound up in System V was never intended as a general
facility.  It exists because a special-purpose application running
on a special-purpose kernel had to move to a generic kernel, so they
stuck in a special-purpose IPC.  Unforunately, `they' were USDL,
the group in charge of System III.

Now you know. :-)
