// Demonstrate that moving the "acquire" in iderw after the loop that
// appends to the idequeue results in a race.
// For this to work, you should also add a spin within iderw's
// idequeue traversal loop. Spinning 40000 times demonstrated the bug
// after about 5 runs of stressfs in QEMU on a 2.1GHz CPU.
