This is a very useful patch, thanks for developing it.

We are using this patch with a different usage. In our environment the stdout
file from Xorg does not last long enough, its gone after the user reboots.

Our xorg-backtrace script writes the analysis into a new log file.

It would match our usage better to have this check for atleast 1 line rather
then 10. Our one line says where we wrote the analysis too.
