// implements Serializable'
// then depending on whether we see A first, we may or may not make B
// serializable.
// The fix is to process them in the right order, ensuring that for a
// type we process its
// supertypes and superinterfaces first. This algorithm may have
// problems with:
// - partial hierarchies (e.g. suppose types A,B,C are in a hierarchy
// and A and C are to be woven but not B)
// - weaving that brings new types in for processing (see
// pendingTypesToWeave.add() calls) after we thought
// we had the full list.
//
// but these aren't common cases (he bravely said...)
