The CF_SHUTW_NOW flag must be handled the same way than the CF_SHUTW flag in co_getblk_nc() and co_getline_nc() functions. It is especally important when we try to peek a line from outgoing data. In this case, an unfinished line is blocked an nothing is peeked if the CF_SHUTW_NOW flag is set. But the blocked data pevent the transition to CF_SHUTW. The above functions are only used by LUA cosockets. Because of this bug, we may experienced wakeups in loop of the cosocket's io handler if we try to read a line on a closed socket with a pending unfinished line (no LF found at the end). This patch should fix issue #744. It must be backported to all supported versions.
