Title: PHP-1020: Remove extra reset() method.

I honestly thought it was part of Iterator, but it is not :-)

I did see whether it was necessary to iterate over a command cursor twice as well, but it is not. You can just do:

$c = $col->commandCursor();
foreach ( $c ) { ... }
foreach ( $c ) { ... }
