[bitbake-devel] [PATCH] daemonize: Ensure child process exits safely

When we create the child, if an exception occurred it was transfering
back into the parent context. We don't want to do that us use a try/finally
to ensure we exit.
We need to ensure a traceback is printed and any queued UI messages which
may not have made it to the client UI at this point.
