[wp-hackers] delete_attachment hook firing too soon to be useful

[Alex Dunae]

In wp_delete_attachment, the delete_attachment action is fired once
all the useful info in the DB is already gone.

I need to be able to figure out the parent of an attachment as it's
being delete to update a playlist file.  Is there any other way, or
should this become a Trac feature request?

FWIW, I'm not the first to be stumped: http://wordpress.org/support/topic/226773
