Comment 1 for bug 1537812

And, here's the branch:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/miker/lp1537812-patron_search_timeout

It is not clear where the long-running queries are coming from, though it is
likely either the actual patron search interface or from the duplicate check
performed during patron registration. Therefore, testing is made particularly
difficult.

This is backport-able, and should be, IMO.
