Ah, thanks Tim!

I had a brief heart-in-mouth moment when the Attachments index took
20-some minutes to build, blocking inserts in the process, but now I can
shred 10 tickets in about 3 minutes - about 20 times faster.

I've also enabled the slow-query-log, so I can perhaps tune it a bit more.



(my case is for 3.6.4, incidentally)
