Robert Watson 76f6939888 Expand the scope of the socket buffer locks in sopoll() to include the ... state test as well as set, or we risk a race between a socket wakeup and registering for select() or poll() on the socket. This does increase the cost of the poll operation, but can probably be optimized some in the future. This appears to correct poll() "wedges" experienced with X11 on SMP systems with highly interactive applications, and might affect a plethora of other select() driven applications.
