setgroups() behavior

[John F. Haugh II]

I'm taking an informal survey.

1003.1 states that whether or not the current effective
GID is returned as part of the groupset returned by
getgroups() is implementation defined.

I am curious what the group's feeling is in general about
permitting the current effective GID to be added via
setgroups() to the concurrent group set using setgroups().

My reasoning is that the concurrent group set =should=
reflect all of the groups being used in determining the
process's access rights.  So, either the system should
add the EGID to the list, or it should permit the process
to explicitly add the EGID without requiring UID 0
privilege.

Please reply by mail, I'll post a summary if there is
enough interest ...
