oops, i missed a step (php_daemon_script) in the chain of calls;
it's : javascript -> php_on_apache -> windows.bat -> php_cli ->
php_daemon_script -> curl_exec -> php_script
followed by calls-until-finished from javascript that read the status of
php_script via json files written to the server and thus display the status
to the end-user..
the windows.bat just starts up cli-php with admin privileges, which executes
the php_daemon_script, which uses repetitive curl calls to the import-script
("php_script" at the end of my chain) that does all the work for a single
item in the total upload/import queue; it does video conversion with
exec(/path/to/ffmpeg), photo conversion with imagemagick, and updates the db
with the php adodb library.
php_script at the end of it's work returns a simple and short status array
(json_encode()d) to the php_daemon_script via curl_exec, that dictates if
the php_daemon_script should continue calling the (import) php_script more
times.
it's curl_exec that hangs/freezes, both with using CURLOPT_RETURNTRANSFER=1,
or capturing output with ob_start() and ob_get_clean(). i've gathered that
much from my custom debug logs.
