User events are processed (poll/select) with FD's so can we just use the

Something like...
5. ib_cm_get_fd( struct ibv_context *device_context) and
ib_cm_get_event(int fd, **event).
I think that this is a good approach. It avoids searching lists when calling
ib_cm_get_event(), but still gives the flexibility of per device event handling.
Plus users don't have to track CM devices separately from verb devices.
ibv_get_async_event(int fd, struct ibv_async_event *event);
ibv_get_cq_event(int fd, struct ibv_cq **cq, void **cq_context);
This makes sense and avoids users from having to map from an fd back to a verbs
defined data structure, that is used to reference the fd. Roland, what do you
think?
