The attach opening or a committed command exceeded its deadline.

A command's deadline starts before queue admission and runs until tmux
closes its response block. Once the connection commits the command for
writing, tmux may execute it. The connection ends rather than reuse a
possibly partial line, so this does not prove a mutation is safe to retry.
