I think this could in some situations, slightly improve the performance
of the ticket search results page.
As you can add linked tickets to the ticket search result, this leads to
one additional query for each ticket, with the default search limit of
50, this are 50 additional queries.

In my case, this is more worse, because I created a custom report where
I have to inspect the links for 1000 tickets, so there are 1000
additional queries. :-(

So maybe this is something that is worth to go into RT 4.2?!

Should I send a PR or will you put this on your TODO list?
