That's open for discussion in this review. My reasoning:

Other than the stress-open-close, none of the other tests actually 
depend on the oa exponent, so we might as well use one value everywhere.

There is one patch on top of this series which should adjust the 
exponent value for all tests so that they run quickly on simulation.  
Maybe I should post the v2 with that patch so the context is clear, 
otherwise, I agree that the reason for these changes is unclear.
