1. $! always set to 9 (or at least is not 0)
2. child_error_exit_value() should also return if child_error_failed_to_execute() ?

open3() said: open3: exec of /bin/zippy failed at /Users/dmuey/perl5/perlbrew/perls/perl-5.16.0/lib/site_perl/5.16.0/IPC/Open3/Utils.pm line 87.
4. Use of uninitialized value in numeric eq (==) at /Users/dmuey/perl5/perlbrew/perls/perl-5.16.0/lib/site_perl/5.16.0/IPC/Open3/Utils.pm line 336.
