Comment(by nickm):

 Well, large uploads will already stall as soon as they hit the stream
 window even if we don't limit them, and will stall immediately without
 optimistic data, so it's no big loss if we have them stall somewhere in
 the middle instead.

 The big win for optimistic data is in protocols where the client opens a
 connection and makes a request immediately, so that optimistic data saves
 a round trip.  If we choose a maximum size that's larger than any
 "reasonable" protocol's "typical" request size, it'll still be a win.

 My hunch says something like 16K will be big enough to get nearly all the
 benefit from optimistic data in nearly all cases.  Moreover If it's a
 client-side parameter, we can tune it later without ill effect.
