If a program (e.g. nixos-install) writes more than 1000 lines to stderr during execute(), then process_serial_output() deadlocks waiting for the queue to be processed. So use an unbounded queue instead. We should probably get rid of the structured log output (log.xml), since then we don't need the log queue anymore.
