Long description

There are two vertical wavy lines labeled Thread 1 and thread 2. The vertical direction depicts time. Thread 1 is split into two parts and one of the parts is labeled Access (Errno set). Thread 1 then travels toward the right for a while, bends down with a downward arrow labeled Open (Errno overwritten). Then thread 2 travels toward the left for a while, bends down with a downward wavy arrow labeled Errno Inspected.
