* Messages written to stderr are logged to loggers with the option kLoggerOption_ConsoleLog set.

The "console" domain is used to log stderr messages. Note that kLoggerOption_ConsoleLog is not a default option, so it must be set explicitly via LoggerSetOptions, such as:

    /* Enable console redirecting to NSLogger */
    LoggerSetOptions( LoggerGetDefaultLogger(), LOGGER_DEFAULT_OPTIONS | kLoggerOption_ConsoleLog );

This is not a default option.
* Log stdout in addition to stderr. Process a line at a time so we don't block the select() thread! Note that we still wait for a full line to be available, though.
* Use non-blocking I/O and do not wait for full lines to be available in stdout / stderr.
* ARC compatibility.
