Re: Patch to retrieve send rights for shared memory objects

[Roland McGrath]

This is a real questionable interface to add.  "Number of send rights" is
really not an appropriate notion for the Hurd protocol object abstraction.
It doesn't even necessarily mean very much useful even in a Mach-based
context.  It may not be really accurate to say anything other than yes/no
to "are there any references other than this one?"
