System.Posix.User is inadequate

There are several problems with this module: 1) There is no way to get all users/groups on the system (getpwent) 2) The UserEntry type does not reflect the Gecos field (pw_gecos) 3) The UserEntry type does not reflect the password field (pw_passwd) 4) The GroupEntry type does not reflect the gr_passwd field This renders is unfortunately useless for some very basic Unix tasks. Is there still time to fix this for 6.6?
