Previously the runInShell and outputForRunInShell methods were
exclusively processed single threaded, meaning all calls
were processed sequentially. With the multiplexed
helper script we can now run multiple processes simultaneously.
( see tst_manual_deviceshell )
Additionally the new script allows us to capture both
stdout and stderr from commands which was not possible previously.
