I take this to mean that it's fine if CQEs _are_ retrieved after a QP is destroyed. Since a CQE does not have a pointer to the QP, but only a QP number and a consumer-defined work request ID, I think this is OK; there's no direct reference to a stale resource.
I was actually thinking about the destruction of the CQ, not the QP. Thinking about it more, it seems unlikely, but couldn't a user destroy a QP followed by the CQ before ibv_get_cq_event() returns?
