This has a problem. For example, to redirect output to a file, I need to
read it from the pipe stream and write it to the file stream myself. If I
want this to happen as the text is generated, I need a separate thread to
"weld" together the pipe stream and the file stream. That is a good deal
clunkier (and less efficient) than is available using Ksh.
