Re:Re: Sorry for interrupting again

Thanks, Henrik pal!

I think disk_io_pending is used to control that more than one
disk read/write events can not perfrom one the same store_client
at the same time. If one event is doing, the another must wait
and using AddEvent to handle it. Am I correct?

Best regards,
George Ma
