> Instead of closing circuits or connections in response to OOM, you could
check whether the relay has hit its rate limit, and if it hasn't, send a
bunch of cells along the circuit/connection. (Perhaps the next relay will
have more room for them.)
That sounds plausible as a reliability improvement, but unless I
misunderstand, it won't actually prevent any DOS here, since the recipient
could just stop reading and thereby make the sender's TCP implementation
refuse to write any more.

practice?
Less than 1000; I don't know how much less.
