Review Comment:
   Instead of `UnsignedInteger.fromIntBits(deletionTimeGuavaUint).longValue()`, 
perhaps we could use `UnsignedInts.toLong(deletionTimeGuavaUint)` and skip the 
instantiation of `UnsignedInteger`.
   
   That method is marked as beta, which is always scary. However, 
`UnsignedInteger#longValue` still calls to it, so we are using the beta method 
anyway.
