> The clear() method inside of {{FilePendingMessageCursor}} is supposed to
> clear any messages in memory, as well as clear any messages in the disk
> pending list by destroying it so it can be reset. There are two bugs in this
> method:
> # Clearing the memory list does not iterate and decrement each reference so
> the memory usage tracker is not decremented on clear.
> # When clearing the disk list, the wrong destroy method is used so while the
> list is correctly destroyed and marked as unloaded, the reference is not
> nulled out. This means that any future writes to the cursor will throw an
> exception because the cursor is not loaded. The correct helper method will
> reset this so that future writes will create a list that is correctly
> initialized.
> The bugs here are not showing up with normal usage because the clear() method
> is generally only called when destroying a durable (and there is already code
> to remove the references before calling clear so memory is decremented)
> however because this method is public and could be easily called in the
> future it should be fixed so it works correctly.
