Me? No. It still uses a thread instead of events, so I don't think it
qualifies as a good example for anyone else wanting to do the same thing.
Lots of hardcoded expectations (specific sleep patterns, rather than
waiting for the kernel to change with a timeout for failure). It doesn't
check all the possible ways that the output maybe changed (and if they
are irrelevent, that too also needs to be tested to establish expected
behaviour and catch future regressions). Important question, how is
userspace expected to know that the vrefresh changed? How do get around
that userspace is expecting a fixed vblank frequency?
