Bug #6731: Out-of-control queries on production server
GES resulting in infinite loop

Description
In response to recent server problems, I've written a diagnostic tool that sends me a notification any time a WP request exceeds 200 database queries. (Some interesting discoveries!!) The reasoning is that the performance problems seem like they're due to a script that is improperly querying the database too much - like a bad loop.
I found some GES behavior that is a bit wonky, and was hoping I could get Ray's eyes on it. A log file is attached (see the query list at the end). A lot of what's happening here is just the result of uncached queries - an independent issue. But, without completely understanding what's happening, there seems to be too much back-and-forth between GES and bp_get_email(). There's a bunch of hooking and unhooking in ass_send_email() - is it possible that there's a load-order issue, so that something that ought to be unhooked isn't getting unhooked in time?
I'm going to continue diagnosing myself, but I wanted to get this in front of you as soon as I could, because you might be able to see something that's not obvious to me.

Yeah, that's a good point. It will help.
On review, I don't think that what's in this log is really an infinite loop. There may be some inefficiencies, though, and it would make sense if it were connected to the BP 2.5 email migration. So please continue to think it over from your end :-D
Also, when I looked at this a few weeks ago, I remember seeing the BP deprecated email filters firing a lot during the email sendout runtime. Maybe we can disable them? If not, we can post a ticket upstream.
Perhaps we can use BP_IGNORE_DEPRECATED? I know there were some issues in BP 2.7.x with this, but maybe it's worth giving it a shot on cdev?
Sure, if we can ignore deprecated across the board, that'd be a win.

The efforts made in #10605 means we can close this one out.
