DF-0851: 3000 mounts of /tmp/df0851.iso via /dev/vn0, 8 I/O-pressure children
DF-0851 RESULT: 3000 ok, 0 failed(EIO), 0 failed(other)
DF-0851: No EIO failures in 3000 tries. Race did not trigger.
  EXPECTED: the brelse->deref window (lines 437-465) has no I/O,
  so the B_AGE buffer is virtually always still in cache.
  Bug confirmed by code-level trace; not reliably triggerable.
