They sure are, but I have no idea if they are really needed:
...
init_locks()
lock_callback(9, 2, ex_data.c, 203)
lock_callback(10, 2, ex_data.c, 206)
lock_callback(9, 2, ex_data.c, 270)
lock_callback(10, 2, ex_data.c, 274)
lock_callback(9, 2, ex_data.c, 304)
lock_callback(10, 2, ex_data.c, 325)
lock_callback(5, 2, ex_data.c, 413)
lock_callback(6, 2, ex_data.c, 424)
lock_callback(9, 30, eng_list.c, 284)
lock_callback(10, 30, eng_list.c, 291)
lock_callback(9, 30, eng_lib.c, 116)
lock_callback(10, 30, eng_lib.c, 116)
lock_callback(9, 1, err.c, 295)
lock_callback(10, 1, err.c, 298)
thread_id()
lock_callback(9, 1, err.c, 446)
lock_callback(10, 1, err.c, 458)
lock_callback(9, 1, err.c, 446)
lock_callback(10, 1, err.c, 458)
lock_callback(9, 1, err.c, 513)
...
Some 55,000 of these for a two-core OpenCL-CPU self-test.
