When performing any action which requires pakfire, the page gets locked with an message informing the user that pakfire is working. The page will be reloaded when pakfire has been launched and is doing the requested operation - showing the well known log output. This also happens when pakfire has been launched via any kind of terminal or SSH session and the CGI gets accessed. Internally before pakfire gets started a variable called page_lock will be set to lock the page. An while loop will keep the page locked until pakfire is launched fully and has written it's lock_file. This approach will prevent us from any kind of required time intervall or race conditions.
