You might want to pass the log file FD along as well. An audit of what
is currently preserved across reset would help figure out what else
should be saved.

(note that execve wouldn't change the PID...)

You'd have to close file descriptors, and probably figure out how to
deal with DRM too.

Frankly, I suspect that doing the reset in DIX would end up easier
than fixing the drivers to deal with execve, but either seems a lot
easier than the current code...
