--- Comment #13 from Stefan Dösinger stefandoesinger@gmx.at 2007-12-07 15:41:50 --- I'm sorry, but a user mode application must not be able to crash your system. This is how modern operating systems are defined. No matter what evil thing the app does, either maliciously or accidentally, the kernel must protect you from harm. If it does not, the kernel is broken.
Get any good book about operating system that discusses topics like security, multi-user systems, resource quotas and similar things. They will all confirm what I said.
Even if Wine is the old application on earth that crashes your system: If the system crashes, and you are not running Wine as root, it is a bug in your kernel, not wine.
