Note that the security draft, section 7.5.2.4, walks through DoS attacks
on the RDMA Read Request Queue. Technically, the attack described on
this thread is not a DoS attack unless the RDMA Read Request Queue is
shared by multiple connections (the security draft walks through
normative mitigations to solve this). If it is a single connection, the
only person you're hurting is yourself - thus this isn't DoS - but it is
a bug.
