** Summary changed:

+ readSet is a nasty lie that leads you in circles and then makes you cry

** Description changed:

  HailDB always respected readSet to only read the columns that would be
  needed for any particular operation.

  In read/write sysbench, this turns out to be a lie and we weren't
  fetching all the columns needed to properly execute the queries.
  
  you'd see a DELETE on a secondary index followed by an INSERT and the
  INSERT wolud get duplicate key, where clearly that's impossible.
  
  so ignoring readset fixes it, but this is just dumn - we should be able
  to optimise here and not always pull every silly column off disk.
