    Peak-memory usage for T3064 varies depending on whether .hi file exists on not
    
    Really, the existence or otherwise of the .hi file shouldn't affect validate
    output, but it seems to.  Maybe 'make clean' doesn't clean enough?
    
    In ay case peak memory usage is a fragile number because it depends on when
    GC happens.
    
    So I increased the range to 20% for now.
