If I simply pclose the process it has the same effect - the other spawned processes keep running. I figured out what's happening is the lame process keeps going utnil it finishes, and apparently is sending its data to the proverbial bit bucket... and in a process tree it moves from being under the http process to being under init itself... fm

Use something else to pass the data back to the user... popen() comes to mind or proc_open(). Then disable auto abort on user disconnect via ignore_user_abort(). Then after sending periodic data chunks, check the user connection status via connection_aborted(). If your script finds that the user has aborted, then kill all the processes in the pipeline from the PHP script before finally aborting the PHP script itself.
