    malloc debugging is disabled in 5.0-R and 5.1-R. Once we hit
    5-STABLE it will be turned off for good in the branch.

    It would be interesting to see if the recent locking of the ATA driver
    has any benefit on these tests. Of course if you update to 5-CURRENT
    then you'll need to disable INVARIANTS, WITNESS, and malloc debugging.
