oh dear. i didn't realise the linuxulator was that broken.
maybe somebody running the HEAD branch could test the driver and see if linux apps work. i had a quick look at the linuxulator sources using webcvs and they comitted quite a lot of changes recently to it.
i also did a bit of debugging and at least doom3 dies after issueing a linux_sys_futex syscall and that's exactly the syscall the recent commits to HEAD are dealing with.
