--------------------------------------

Hi Ray,
What does the RI behave if one is accepting and another is trying to change the block mode?

>From the native aspect, when accept is called for a blocking socket, it should be blocked. So if we have configure it as block and accept, the process should be put to sleep. During this sleep, if we change the blocking mode, it should not have any affect.
