No need to have a field. (But having code in the constructor really
helped exposing errors in derbyall, since the constructor is run far
more frequently than getHoldability().)

It seems like all places a new TemporaryRowHolderImpl is created, an
Activation is readily available. Would it make sense to simply pass
that activation down to the TemporaryRowHolderImpl object and further
down to the TemporaryRowHolderResultSet?
