Argh, yes.

Yes, this needs fixing.

But DOS batch scripts make me sad, so I was thinking that I could just replace 
the contents of startxwin.bat with something like "%RUN% startxwin.sh"

Is there a reason why we can't do 'checkx -d %DISPLAY% -t 30' rather than 
counting up to 30 ourselves?

This also adds run2 as a dependency of the xinit package which owns these scripts.
