Naturally. Same goes for BugTask:+index - which I've added a column to
BugMessage to address, but haven't yet had time to go back and start
populating - not everything is a low hanging fruit :).

If we drop the default timeout to 5 seconds, will that cause the
number of POFile:+translate timeouts to shoot up wildly? If so, I
think we should keep the exception and have a bug open: the bug would
be prioritised to the top of your kanban board backlog, and thus you'd
get on to it fairly soon.

If on the other hand the page is usually under 5 seconds, then sure,
we can have it track the default timeout and see what happens as the
default is lowered.

https://devpad.canonical.com/~lpqateam/ppr/lpnet/latest-daily-pageids.html
says that the 99% percentile time for that page yesterday was 5.14
seconds on 7300 page loads: thats pretty good for now, and I'd expect
that we can get by without an exception, so lets get it removed.
