The Tru64 shell does not like us to close stdin. It will corrupt its
memory which will become apparent when FD operations are done the next

I've applied the patch below to HEAD to finally fix this issue.
Gary helped me analyze it -- many thanks to everyone that provided
input to this!
Cheers,
Ralf
