Why use pipeShell instead of spawnShell? And why 
`cast(Redirect)0`? It's not necessary. Also note that shell 
commands (incl. system) take one string argument, not an array.

This can be a simpler one-liner: wait(executeShell(cmd))

So, the deprecation message is not far off, perhaps missing a 
`.wait()`.

You mean it does wait until completion?
