Joel Dice 3d18f88ad9 fix Runtime.exec bugs
The first bug affected POSIX systems: if the app never called
Process.waitFor, we'd never call waitpid on the child and thus leak a
zombie process.  This patch ensures that we always call waitpid by
spawning a thread to handle it.

The second bug affected Windows systems: we weren't closing the
child's ends of the stdin, stdout, and stderr pipes after process
creation, which lead to us blocking forever while reading from the
child's stdout or stderr.
