That being said, I would still expect the code not to allow _this_ kind of effect on the entire system when two alledgely incompatible operations run simultaneously. I mean, Linux is a multi-user, multi-tasking operating system where one simply cannot expect all processes to be cooperative to each other. We have the operating systems to prevent this kind of issues, not to cause them.
