I think it's a bug. Quote from spdy2 spec:
"Receivers of a PING frame should send an identical frame to the sender as
soon as possible (if there is other pending data waiting to be sent, PING
should take highest priority)."

eues the ping reply and doesn't send it until it gets a response from
upstream.
I added a call to ngx_http_spdy_send_output_queue() in
ngx_http_spdy_state_ping() to send the PING reply immediately and it solved
the problem.
