Details

Things like recursive descent parsers (esprima is a good test case) will have very regular frames, but widely varying tails. Would be interesting to see how much more compact we get by making SavedFrame a (parent ptr, async parent ptr, content ptr) triplet where content is (function name, source, line, column).
