The Linux Kernel version 2.6.25 introduces a new Linux process sleeping state, TASK_KILLABLE: If a process is sleeping killably in this new state, it works like TASK_UNINTERRUPTIBLE with the bonus that it can respond to fatal signals. This feature is generally an improvement over the existing options -- after all, it is another way to keep from getting stuck with dead processes.

preap removes zombie processes, i.e. processes that have exited but whose exit status has not been collected yet. The article isn't about zombie processes though, but rather about processes that sleep indefinitely and uninterruptably in kernel mode.
