I found a problem caused by this series.

As this series use exec_local_req() for
pull/push/forward_read_xx/forward_write_xx methods, when the cluster
become busy, all io/gateway threads may call exec_local_req() and wait
in eventfd_read() at the same time, then there are no other idle
threads to do local request, as a result the cluster are blocked by
itself.
