I have misplaced my haskellwiki login right now, but...

Under section 2:

  MissingH already provides a whole slew of forking/popen code; see
  http://software.complete.org/missingh/static/doc/System-Cmd-Utils.html

In particular, you seem to be wanting my pipeBoth function.

Note that your proposed String -> IO String function type is insufficient
because it does not provide a way to evaluate the return value of the
function.
