 *
 * The process reaper ensures that a process is not freed immediately after it is killed. This is important because
 * other processes may still wish to access information about the process, such as its exit status.
 *
 * The reaper runs periodically and frees any "zombie" processes when they have no remaining threads by deinitializing
 * its `/proc` directory, when none of the proc files or directories of the process are open its resources are finally
 * freed.
