Hello Mark,
Next iteration of the patch(es) are ready, hosted on Github (git
request-pull output below). I think most of the issues we've discussed
have been addressed; the setup with stdatomic.h is a little WIP, I
wasn't certain how it should be done moving forward (and, I'm not all
that familiar with Autotools). The one extra line in dwarf_getcfi.c is
to account for a failure in the test suite when Valgrind is enabled
(didn't catch it the first time around).
I like the idea of "owner" threads (and I think it should be simple
enough to implement), but I'd like to do some performance comparisons
against the pthread_key_* option before adding too much more complexity.
