It really depends on how much control on the life cycle of state exists between the user, program and operating system. More to the user, easier to press reset and clear the state. More to the OS then it needs to have some clear guidelines about how to deal with bad behaving programs. If its all up to the programs then it will probably be very brittle since applications may not implement what's needed to clear state when necessary. Although if a program crashes you'd expect that the OS would clear its state.. which I assume is the case.
