Ian Norden 59cdaa05e6 moving some memory allocation to init function rather than within
execution cycles and fixing test db tear down so that it drops
checked_headers table instead of individual columns (droping columns
only hides them, they remain in memory and continue to contribute to the
1600 column limit which causes us to eventually exceed it)
