But I don't think there should be any requirement to make resolving a trace be async-safe. There's rarely going to be anything useful you could do with such a trace that would also be async-safe; it'd be better to require that this be done in regular context instead.

::write is async-safe. You can write it to a file or stderr or a pipe or a socket.
