59cd7894d9 FEATURE: if site is under extreme load show anon view
If a particular path is being hit extremely hard by logged on users,
revert to anonymous cached view.

This will only come into effect if 3 requests queue for longer than 2 seconds
on a *single* path.

This can happen if a URL is shared with the entire forum base and everyone
is logged on

47c44356f8 FIX: load balanced servers do not share monotonic clock
This means then when a service is load balanced and you reach rate limits
there was a case where they counting was way off

also remove the stub from clock_gettime cause we need to be super careful with
it, so we should probably just stub by hand when needed
