Hi there.
Yeah, I was reading about the OOM killer in linux, and how a few bad design
choices a long while ago is creating quite a few issues today.
Thanks for looking into this. Richard is doing other stuff at the moment,
and not concentrating on openmovieeditor so much these days. It's a pity, as
openmovieeditor is a very useful program. On the other hand, I do not blame
Richard, it's his life and he can do with it whatever he wants.
It just makes me wish that I knew how to program so I could fix these things
myself. Still, openmovieeditor continues to work fine, so it's no big issue
at the moment.
