[Alfred M. Szmidt]

Same here, explanation behind the changes, why etc.

2006-01-02  Samuel Thibault  <samuel.thibault@ens-lyon.org>

        * task.c (task_init): Call new machine_task_module_init() function.
        (task_create): Call new machine_task_init() function.
        (task_deallocate): Call new machine_task_terminate() function.
        (task_collect_scan): Call new machine_task_collect() function.
        * task.h: Include <machine/thread.h> for machine_task_t.
        (task): Add new machine member.
