    Non-interactive stdin is always available for reading.

    Failing to set the 'stdinOwned' flag meant that you could never read from
    stdin which wasn't a terminal. Oops.

    Allow background nickle to not poll on tty ownership

    When stdin is connected to a terminal but nickle is not the foreground
    process on that terminal, the io code would poll to wait for ownership to
    flip back to nickle so that reads could be performed without generating a
    signal. Now, nickle waits until someone actually tries to read from the
    terminal before starting to poll. This means that simple background
    processing nickle programs will not poll every 100ms.

    Remove support for non-SIGIO pipes

    Older version of the kernel (before 2001) failed to generate SIGIO on pipes,
    so nickle had code to poll instead. I think we can safely remove that code
    now.

    Avoid having the 'pretty_print' builtin show two error messages.

    NamespaceLocate takes a 'complain' boolean that will print out an error
    message, but the pretty_print command also raises an exception when it fails
    to find the name. Two errors is at least one too many here.
