This problem still exists, althrough now the limit is 65535 (run getconf
NGROUPS_MAX), and it takes "id" 30 minutes to run.
I propose the following behavior.
When called without a username argument, and
getgroups() >= sysconf(_SC_NGROUPS_MAX),
or when called as id <user>, use a loop counter; test if this value
ever exceeds that of sysconf(_SC_NGROUPS_MAX)
error(0,0, "User '%s' may be a member of more"\
"groups than the system allows\n", pw->pw_name);
