elfdump encapsulates a lot of ELF knowledge, and might be harder

I'd like to know how long wsdiff takes to run, and how much of

We're also open to ideas for elfdump to make it more wsdiff-friendly.
I'm guessing that the cost of a single invocation of elfdump isn't
the bottleneck when compared to the cost of running it multiple times.
Do you have a sense of how bad elfdump's overhe

That's a lot of interesting comments.
Side note: I think think the dump+elfdump combo is used to provide more
robust diff detection (to prevent a case where the actual difference
gets lost thanks to an error in elfdump pretty printing functions) and
also to push the complex
