I really need to be able to specify the uid of users
that I create. I wonder if the code to assign a users
id could be changed to something like the following.

if ($user->isNew()) {
if($user->getVar('uid'))
$uid = $user->getVar('uid');
else
$uid =
$this->db->genId($this->db->prefix('users').'_uid_seq');
