tracd fails when running as a daemon

[Matthew Good]

Running tracd with the "-d" option starts it as a daemon process, but every request fails without a response. On the command line I see "Unhandled exception in thread started by" which also indicates that the process has not actually been fully daemonized (I know that there's a cookbook recipie on how to do this that I'll check tomorrow).

In trying to debug the problem I commented the lines that close stdin, stdout and stderr so that I could see more information, and it worked again, so it's likely to be a problem with trying to write to these closed streams.

The code below will redirect the streams to /dev/null and it will work again. I'm not sure if this code is windows comptatible tho.

    try:
        if daemonize:
            pid=os.fork()
            if pid == 0:
                os.chdir(os.sep)
                os.setpgrp()
                # Redirect standard file descriptors
                sys.stdin = open('/dev/null', 'r')
                sys.stdout = open('/dev/null', 'w')
                sys.stderr = open('/dev/null', 'w')
            else:
                print 'tracd daemon running with pid: %d' % pid
                sys.exit(0)
        httpd.serve_forever()
    except OSError:
        sys.exit(1)

It wasn't windows compatible before either…

Looks good.
