I don't like this. 0.1 s is less noticeable than 1 s for interactive
human users, but for applications it may be way too much.

We really should start thinking on a better solution to handle I/O.
Unfortunately, seeing the cold feet reaction to something as benign as
AVWriter, I am not confident this project has what it takes to go in the
right direction.
