Just one video stream right now. This one "master" would grab and
compress, but these tasks would be delegated to libjpeg etc, so it's
more about copying data around on the python side. I would expect
these video frames to be around 15-20 kilobytes each. And it's for our
web pages (tha place I work for), nothing too serious really.

Yeah, sorry if I gave too little info. It seems that I am running in forked
mode, as apache.mpm_query(apache.AP_MPMQ_IS_FORKED) is
true, and _IS_THREADED is not true. This is how it was pre-configured
out of box. I'll investigate further.
