Can I insert my pet peeve here?  There is also a need for a standard
auxiliary output.  stderr is often pressed into service for non-error
output.  I claim that this is a bad thing.  It is a pain to scan through
verbose output checking for error messages.  There should be a standard
place to send a 2nd data stream seperate from the error messages.
I run into this problem much more frequently than the case of needing
two input streams.

A second input stream could be useful for other things besides commands,
perhaps call it auxin?

So, how about: stdin, auxin, stdout, stderr, and auxout ?
