I agreed with Æver's suggestion exectly because I failed to read the
above motivation from the patch.  If you are trying to find out who
called, then you'd need to do the "find the parent process" dance
when your parent did not give you their SID to append your ident to.

Perhaps it was obvious to the author of the patch, but it was
unclear from the point of view of readers.  Perhaps the first
paragraph of the proposed message wants a bit of rephrasing.  "we
aren't sure exactly ... how, why, etc." part of the above really
helped.

Thanks.
