reorder exit code to defer stdio flush until after dtors
this is required in case dtors use stdio. also remove the old comments; one was cruft from when the code used to be using function pointers and conditional calls, and has little motivation now that we're using weak symbols. the other was just complaining about having to support dtors even though the cost was made essentially zero in the non-use case by the way it's done here.
