As a Mac user, and former Linux and Windows user, I really miss having ctrl-alt-del available (you may think "why do you need ctrl-alt-del in a mac? the OS is perfect and never crashes!" and I must answer: "my friend, stop drinking so much kool-aid, it's hurting your brain"). My problem is that even though both mac and linux have a myriad of ways of listing the processes and killing them, when the computer is hung up they don't seem to respond in the same way as ctrl-alt-del in Windows does.
Allow me to clarify: I have this (possibly romantic) idea that when my computer was hung up in windows, pressing ctrl-alt-del would bring up the dialog (which sort of depends on the version of the OS, it used to be only the process manager but I believe it evolved to something else in the meanwhile) even if no other process would start or advance at all. This is the crucial difference: from what I understand, the process managers and such in mac and linux are just yet another process, which being treated as such may not start at all (or take two days to do so, if the computer is really hung up), whereas in Windows the process manager always comes up fairly quickly unless in the case where there has been a serious crash and reset is the only solution.
What is your say in this? Am I being too romantic and the process manager in windows is exactly the same in any other OS, is there something to objectively differentiate it, or am I using the wrong process managers in mac/linux?
