stderrFeed

output.
Process will begin outputting data to all OutputFeed for stderr
upon the first attachment of OutputFeed.
If Stdio.Config.stderr is not Stdio.Pipe, this does nothing. If the Process has been destroyed, this does nothing.
Attaches multiple OutputFeed to obtain stderr
output. This is handy at Process startup such that no data is missed if there are multiple feeds needing to be attached.
