David Shrewsbury 7225354ec0 Add a timeout for the image build ... A builder thread can wedge if the build process wedges. Add a timeout to the subprocess. Since it was the call to readline() that would block, we change the process to have DIB write directly to the log. This allows us to set a timeout in the Popen.wait() call. And we kill the dib subprocess, as well. The timeout value can be controlled in the diskimage configuration and defaults to 8 hours.
