 The following code, line 535ish of wp-includes/user.php

 {{{
 $metavalues = $wpdb->get_results($wpdb->prepare("SELECT meta_key,
 meta_value FROM $wpdb->usermeta WHERE user_id = %d", $user->ID));
 $wpdb->show_errors($show);

 if ( $metavalues ) {
     foreach ( (array) $metavalues as $meta ) {
         $value = maybe_unserialize($meta->meta_value);
         $user->{$meta->meta_key} = $value;
     }
 }
 }}}

 This does not work for meta keys that have multiple values.  Right now
 get_usermeta doesn't act according to spec because this fills the cache it
 pulls from.
