Prevent the parser function #ifexist being used more than a certain amount on error
pages. The maximum number of #ifexist queries can be set in $wgMaxIfExistCount, which is,
by default, 100. Any more uses over here will default to the "else" text. Done
to discourage templates like Template:highrfc-loop on enwiki, which willingly does
something like 50 database queries for a template that is used for many users on one page.
Clearly suboptimal from a performance perspective.
Is there any way, instead, to defer these so they can be done all at
once? Tim, do you have any thoughts on whether this is reasonable?
(I would suspect not, but it doesn't hurt to ask.)
