   (Shrug) What about redirecting one of the streams to another file
   handle?  I think any modern platform will support this.  We could, for
   example, make this an option (it could be on by default if PTYs aren't
   supported).

Terminals are quite different from "normal" pipes.  For example stdio
is line buffered for (pseudo) terminals but normally buffered for
other streams.  So this affects basically any program.
