 == Overhaul of System.Process ==

 From the patch:

 {{{
 Tue Apr 22 15:02:16 PDT 2008  Simon Marlow <simonmarhaskell at gmail.com>
   * Overhall System.Process

    - fix #1780: pipes created by runInteractiveProcess are set
      close-on-exec by default

    - add a new, more general, form of process creation: createProcess
      Each of stdin, stdout and stderr may individually be taken
      from existing Handles or attached to new pipes.  Also it
      has a nicer API.

    - add readProcess from Don Stewart's newpopen package.  This
      function behaves like C's popen().

    - Move System.Cmd.{system,rawSystem} into System.Process.  Later
      we can depecate System.Cmd.

    - Don't use O_NONBLOCK for pipes, as it can confuse the process
      attached to the pipe (requires a fix to GHC.Handle in the base
      package).

    - move the tests from the GHC testsuite into the package itself,
      and add a couple more

    - bump the version to 2.0
 }}}

 Haddock for the new API is here:

 Patch is attached.  So far I've only modified the Unix parts of the code,
 the Windows parts still need to be updated.

 Discussion period: 4 weeks (20 May)
