Eddie:
Perhaps there is also a literary purpose for DD's visit and his
behavior: It's safe to assume that Rowling knows at the beginning of
HBP that Dumbledore won't survive to the end of the school year.  So,
she wants to give DD a chance to do the things he ought to do to be
sure Harry is ready to go off on his own:

1) DD makes a personal visit to the Dursley's to give them a piece of
his mind and to reinforce his pact with Petunia.  (Also, DD's personal
appearance reinforces the increased danger Harry is in.  DD won't let
Harry travel to the Weasley's on his own.)

3) By the end of HBP, DD makes sure Harry has ALL the info he
(Dumbledore) has, as well as his speculations

4) DD gives Harry a task to accomplish on his own (Sluggy's memories)
to verify that Harry is ready to be on his own.  (Note how nicely this
parallels the theory that Draco is doing a task of his own.)

It's even possible that Dumbledore suspects he is dying as a result of
his wounded hand, or maybe he's (correctly) concerned about his
ability to survive another encounter with a horcrux.  That suspicion
would act as a catalyst to plot with Snape re: how to use his
(Dumbledore's) death to their best advantage.

It's all speculation upon speculation, but for me this all makes a
tighter piece of literature.
