Advice on writing Daemon in PHP/CI or ?

Hey Dave. I guess what I most concerned with about using PHP/CI is the spawning. Does each time an ajax message comes into the server, a brand new copy of the PHP code (ie, a process) is spawned? Thus this is a multiprocess solution, which might be OK, except that I'd be concerned about the time it takes to load a new copy of the process from the disk. Thanks for bringing a little sanity into my plan!
