  * System calls are transformed into request messages to the SYS task that is

  * into a message with type SYS_CALL that is handled in a function do_call().

+ *   Jun 21, 2005   created SYS_NICE for nice(2) system call  (Ben J. Gras)
+ *   Jun 21, 2005   created SYS_MEMSET to speed up exec(2)  (Ben J. Gras)
+ *   Apr 12, 2005   updated SYS_VCOPY for virtual_copy()  (Jorrit N. Herder)
+ *   Jan 20, 2005   updated SYS_COPY for virtual_copy()  (Jorrit N. Herder)
