An old ld-linux.so hole
...ss ratio. Section V. Scenario 3. Let''s try to force a context switch immediately after spawn.c calls exec. spawn.c should open a file (called .lock ) receiving descriptor lock_fd and set a close-on-exec flag on it. Then spawn.c executes flock(lock_fd,LOCK_EX). Another program ( called noloop ) opens .lock and performs flock(noloop_fd,LOCK_EX) as well ( and goes to sleep).
