def capture(block)
  # We delay loading tempfile until it is actually needed because
  # we want to minimize stdlibs loaded so that users who use a
  # portion of the stdlib can't have passing specs while forgetting
  # to load it themselves. `CaptureStreamToTempfile` is rarely used
  # and `tempfile` pulls in a bunch of things (delegate, tmpdir,
  # thread, fileutils, etc), so it's worth delaying it until this point.
