> Was digging into a problem with [~ankit.singhal] where setting RPC quotas on number of requests wasn't having any effect on a multi-Get
> Ankit did enough digging to find that this was because each RPC was being treated as one request instead of the number of requests contained within the RPC itself.
> Thinking as an operator, this is a pretty ineffective control because a user could just craft their API usage easily to work around any kind of limits I want to set to control their impact on the system. TimeBasedLimiter is assuming that one call to the quota code can only count as one request which I think is just wrong.
