Update 1.100 to 1.110
---------------------
1.110 Wed Aug 27 2014
    [ENHANCEMENTS]
    - the 'setpgrp' option can be used to enable/disable the call to
      setpgrp() in the spawned process
    [TESTS]
    - t/10-command.t now ignores environment variables set by ConEmu

1.109 Wed Jul 2 2014
    [BUG FIX]
    - fix the test failures on Solaris, thanks to Wolfgang Pecho
      (RT #82857). The reaper code was actually buggy (since v1.03!)
      and only accidentally worked on platforms where WNOHANG == 1
      (which was most of them)

1.108 Wed Feb 26 2014
    [ENHANCEMENTS]
    - the 'trace' option makes it possible to see exactly which commands
      were spawned, with their options (including environment)
    [DOCUMENTATION]
    - style fixes

1.107 Sun Oct 20 2013
    [ENHANCEMENTS]
    - zombies do not exist under Win32, so no need to warn about
      waitpid return value (many thanks to MITHALDU for his
      continued help in testing on this platform)
    [DOCUMENTATION]
    - removed duplicated NAME section
    [FUN]
    - more zombie quotes in System::Command::Reaper comments

1.106 Sat Oct 12 2013
    [ENHANCEMENTS]
    - brought back System::Command::Reaper, which properly deals
      with zombies
    - execute the command in its own process group whenever possible
      (thanks to Vincent Pit)
    [TESTS]
    - test for the zombie processes is not TODO anymore
    - tests for the timely destruction of the reaper are back

1.105 Sat Oct 5 2013
    [TESTS]
    - add a TODO test for the zombie processes created in certain cases
    - various other test improvements

1.104 Thu Sep 12 2013
    [ENHANCEMENTS]
    - fixed for Perl versions < 5.8.9
    [DOCUMENTATION]
    - minor documentation improvements
    [PACKAGING]
    - switch to Dist::Zilla for maintaining the distribution

1.103 Mon Jul 29 2013
    [ENHANCEMENTS]
    - rewrote the _spawn code to work properly under Plack
    - version 1.100 and 1.102 re-introduced old bugs: they
      have been squished again, and tests fixed to prevent
      re-re-introduction

1.102 Fri Jul 26 2013
    [ENHANCEMENTS]
    - ported an older fix from Git::Repository, to make System::Command
      work with modules that do bad things to STDIN, STDOUT and STDERR
      (thanks to Todd Rinaldo for his 2010 patch to Git::Repository)
      [work done during the patch -p0 hackathon]
