Could we filter both stdout and stderr through functions that timestamp each line, then merge the two and sort on the timestamps?
Unfortunately this wouldn't help---it would be subject to the same reordering race condition. The timestamp value that is added to a line would depend on when the kernel woke up the reading thread/process, so the timestamps wouldn't always accurately represent the time the test program wrote the line. If the kernel woke up the stderr and stdout threads in the opposite order of writing, then the timestamps would be in the wrong order.
