Makes sense. Going through Gnash and identifying these bottlenecks
sounds like a big task, though. If finding these bugs prove easy, I
could attempt to fix them separately from my main project. However, I
don't want to apply for a project that could easily prove very big, and
that I don't currently understand fully. The project does sounds interesting,
