Yes, definitely.  What happens to stderr with this function, by the way?
 Is it tied to stdout (probably the right thing to do), or to /dev/null,
or is it closed (eek!)?  The haddock should make that clear.

It would be useful if there was a readProcess variant that gave back a
String each for stdout and stderr.
