Detailed Description

Capture what one thread prints, without touching any other thread's output.

``contextlib.redirect_stdout`` swaps ``sys.stdout`` for the whole process. In the API, burns run on
daemon threads two at a time: two overlapping flights restored each other's buffers, and the
server went on printing into a StringIO for ever while other requests' prints landed in a run's
notes. Here ``sys.stdout`` is replaced once by a router that sends a thread's writes to that
thread's buffer while it is capturing, and everything else to the real stream.
