It's the opposite of being rate-limited actually.

The only call which is rate limited at the moment is the map call which 
means that it is now quite hard for one person to soak up all the 
resources and delay other people's map requests.

Other calls are not rate limited so if somebody suddenly hits us with a 
big burst of requests it can cause delays for other people - it doesn't 
actually have to be the same type of request, just something else that 
is handled in the same queue.

The plan is to move more calls into cgimap, which means that they will 
be rate limited. It also means they will be more efficient so that 
delays will be less likely.
