I have. What I did was originally based on some of Pierre's comments
that you referenced.
Basically, you leave the MC stack running normally, and you communicate
with it via PHP and sockets.
You'll need to install a PHP script such as this one as the
intermediary:
It is rather crud to use PHP - socket - MC.
The MC socket port listening method is not robust enough, and may went
deaf under some loads.
I think Pierre would disagree. I would also - it's a whole lot more
likely to handle a big load than a CGI that loads the whole engine with
every request.

Problem here most likely is that you are trying to read the entire 300MB file into memory at once. Unless you have an extra 300MB block of RAM floating around, this will start beating on virtual memory pretty hard (and increasingly slow).
