  # Coalese additional queued up events, if any
  # If events keep arriving faster than we can read them off stdin here,
  # we'll never run the script! If you're worried about that, set
  # SECONDS to 0 before this loop and make the conditional also check that
  # $SECONDS is smaller than some timeout to make sure that the script runs
  # every now and then. The stdin pipe buffer size means there won't be an
  # unbounded buildup on stdin -- instead inotifywait will block writing
