Indeed.  That could perhaps stand to have more comment, and is in fact a 
monkeypatch, but I did it that way to be compatible with old versions 
of IPC::Open3.  IIRC, the desired behavior is to have the test process 
STDIN remain attached.

As you noticed, the local() applies to the forked process.
