(re: #1, I'm thinking in part of the ETfW sampling, which is able to capture stack traces from all threads every millisecond and every context switch, among other events, without noticeably slowing down even a high-performance application. Comes in surprisingly handy at times to have capturing that fast, even when doing it more ad hoc rather than sampling.)
Not sure that the library is meant for that: such functionality requires additional care, permissions and probably special compiler support.
I wasn't meaning to imply that it would, just trying to illustrate that capturing traces can be really fast, especially if symbolising them is deferred until later. I'll be interested to see that backend performance information when it's ready (no hurry though).
