this gives us a semblance of a stack trace if async tasks fail, like:
Async task trace (probably incomplete):

it's not much, but it's a lot better than nothing. sadly we're forced
to disable another clang-tidy warning now, but since that one's about
assert side effects being compiled out in release mode and we've long
since decided to just not do that we are not affected by this at all.
also see #724 for a related but different approach to origin tracing.
