Hello Darren,

------ manual cut --------
The system() call also tries to automatically flush the web server's
output buffer after each line of output if PHP is running as a server
module.

Hehe. The problem is not in flushing ability of system() foo, but
flush() itself is not working :(
I've tried to install PHP as a module (as written above), cgi,
compiled with apache. But nothing worked.
