This is the implementation of parsing the SFrame section in an ELF file.  

Presently x86_64-only, it seems.  Can we expect to see this implemented
for other architectures?

Yes, and Jens is here to port it to the s390 :-)

Currently Peter Zijlstra and I are updating the deferred unwinder. Jens is
working on getting sframes to work with it. His interest is getting it for
s390 whereas ours is for x86.

Would a selftest for this be appropriate?  To give testers some way of
exercising the code and make to life better for people who are enabling
this on other architectures.

Yes we should definitely have selftests. But we are far from getting there.
One requirement is that the toolchain used to build the test must support
adding sframes.

In what tree do you anticipate this project being carried?

It will likely go between tip or my tree.
