-///     handles the exception once processed.  Finally an index into the actions
-///     table.
-///  2. The action table, in our case, is composed of pairs of type ids and next
-///     action offset.  Starting with the action index from the landing pad
-///     site, each type Id is checked for a match to the current exception.  If
-///     it matches then the exception and type id are passed on to the landing
-///     pad.  Otherwise the next action is looked up.  This chain is terminated
-///     with a next action of zero.  If no type id is found the the frame is
-///     unwound and handling continues.
-///  3. Type id table contains references to all the C++ typeinfo for all
-///     catches in the function.  This tables is reversed indexed base 1.
