I'm testing the latest trunk under Darwin and i've some strange
benchmark stop with flow control messages:
$./cpgbench
54115 messages received 1 bytes per write 10.004 Seconds runtime

55599 messages received 4001 bytes per write 10.000 Seconds runtime

51113 messages received 5001 bytes per write 10.000 Seconds runtime

10245 messages received 6001 bytes per write 10.000 Seconds runtime
1024.538 TP/s 6.148 MB/s.
0 messages received 7001 bytes per write 10.000 Seconds
runtime 0.000 TP/s 0.000 MB/s.
At the time the message rate go down on the corosync log:
Aug 22 9:59:57.590518 [IPC ] Enabling flow control [401/800] - [0].
Aug 22 9:59:57.753496 [IPC ] Disabling flow control [403/800] - [0].
to my understanding flow control will slow down when overflowed but
restart the flow when ready to process more data?
