Ahh...
int To_daemon(void)
{
Set_full_group( DaemonUID, DaemonGID );
To_daemon_called = 1;
return( seteuid_wrapper( DaemonUID ) );
}
Note that we are doing 'Set_full_group()' here...
This little gem is used so that we set all of the user and group
permissions to the 'correct' ones.
This calls: getpwuid(euid)
and then calls 'initgroups(user,pw->pw_gid)'
I suspect foul play here. You could instrument this and
see if this is the source of the problem.
There are two ways to solve this:
a) Violate the chastity of the permissions system and
brutally set only the EUID.
b) Find out what is slowing down 'To_daemon()' and fix it.
