Comment (by teor):

 Sounds like it will solve our current problem with uncompressed requests.
 So we could merge as it is.

 But what if the DoS switches to compressed requests?

 When we are rejecting uncompressed requests, can we look at the write
 limit for compressed client requests?
 Seems like a simple change that could be really useful.

 I don't think we need to be worried about the DoS switching to relay
 requests. That's a significant amount of error time for an attacker.
