Hibernate is a small utility for Android devices which allows you to hibernate selected background processes. It "kills" them by means of the internal killBackgroundProcesses used internally by Android to free up resources. This method differs from killing applications in the system list of running processes in the way, that it allows applications to save their state before exit, so when you return to the hibernated process back, it will be restored to its previous state.

The utility can be useful for developers who need to test how their applications behave while being unloaded and re-loaded by the system, as well as for other users searching for a way of system optimization on-the-fly.
