Some HTTP/2 implementations are vulnerable to a reset flood, potentially
leading to a denial of service. The attacker opens a number of streams and
sends an invalid request over each stream that should solicit a stream of
RST_STREAM frames from the peer. Depending on how the peer queues the
RST_STREAM frames, this can consume excess memory, CPU, or both.
