Detailed Description

The dispatcher dispatches threads and, by that, puts the scheduler's decisions into action.

The dispatcher manages the life pointer that refers to the currently active thread and performs the actual switching of processes. For single-core systems, a single life pointer is sufficient, as only a single thread can be active at any one time. On multi-core systems, every CPU core needs its own life pointer.
