In D, there's a pointer to the vtable and another pointer to a Monitor object (used for synchronized methods). There was talk about getting rid of the Monitor field years ago, but nothing has happened yet.

Very interesting: is the monitor field ever touched by compiled D code at any point nowadays? Or is it just vestigial?

It's (lazily initialized and) used by the `synchronized(<expression>)` statement (ยง3 of https://dlang.org/spec/statement.html#synchronized-statement) and the mentioned `synchronized` class methods (https://dlang.org/spec/class.html#synchronized-methods).
