Are you saying that Dwarf information should be unwound in realtime or that it should use framepointers and debug information to trivially sample the stacks and record the symbols?

If you have framepointers and debug information, it is both high resolution and fast. DWARF is a fallback for not having framepointers.

If you are saying the DWARF information should be processed at the point of use and not copied and processed later, then I concur. But we should also encourage folks to compiled WITH `-fno-omit-frame-pointer` and `-g`
