T3064 failures

[David Feuer]

I don't know what's going on, but T3064 is giving some substantial
performance trouble, making all the validations fail:

max_bytes_used value is too high:
    Expected    T3064(normal) max_bytes_used: 13251728 +/-20%
    Lower bound T3064(normal) max_bytes_used: 10601382
    Upper bound T3064(normal) max_bytes_used: 15902074
    Actual      T3064(normal) max_bytes_used: 17472560
    Deviation   T3064(normal) max_bytes_used:     31.9 %
bytes allocated value is too high:
    Expected    T3064(normal) bytes allocated:  385145080 +/-5%
    Lower bound T3064(normal) bytes allocated:  365887826
    Upper bound T3064(normal) bytes allocated:  404402334
    Actual      T3064(normal) bytes allocated: 1372924224
    Deviation   T3064(normal) bytes allocated:      256.5 %

I don't know what's allocating an extra gigabyte, but unless there's a good
reason, someone probably needs to tighten something up.
