Review request for 5049299

[Martin Buchholz]

I've been working on clone+exec.
I now have a perhaps-ready-for-prime-time implementation
that appears to fix the problem on Linux
and also includes some new tests for script invocation

http://cr.openjdk.java.net/~martin/clone-exec

This change conflicts with Michael's changes for Solaris.
We'll have to work something out.
My changes are designed to have no effect on Solaris,
but I have done zero testing there.
