 	 *  ループ回数の設定
	 *
	 *  並行実行されるタスク内での空ループの回数（task_loop）は，空ルー
	 *  プの実行時間が約0.4秒になるように設定する．この設定のために，
	 *  LOOP_REF回の空ループの実行時間を，その前後でget_timを呼ぶことで
	 *  測定し，その測定結果から空ループの実行時間が0.4秒になるループ回
	 *  数を求め，task_loopに設定する．
	 *
	 *  LOOP_REFは，デフォルトでは1,000,000に設定しているが，想定したよ
	 *  り遅いプロセッサでは，サンプルプログラムの実行開始に時間がかか
	 *  りすぎるという問題を生じる．逆に想定したより速いプロセッサでは，
	 *  LOOP_REF回の空ループの実行時間が短くなり，task_loopに設定する値
	 *  の誤差が大きくなるという問題がある．
	 *
	 *  そこで，そのようなターゲットでは，target_test.hで，LOOP_REFを適
	 *  切な値に定義するのが望ましい．
	 *
	 *  また，task_loopの値を固定したい場合には，その値をTASK_LOOPにマ
	 *  クロ定義する．TASK_LOOPがマクロ定義されている場合，上記の測定を
	 *  行わずに，TASK_LOOPに定義された値を空ループの回数とする．
	 *
	 * ターゲットによっては，空ループの実行時間の1回目の測定で，本来よ
	 * りも長めになるものがある．このようなターゲットでは，MEASURE_TWICE
	 * をマクロ定義することで，1回目の測定結果を捨てて，2回目の測定結果
	 * を使う．
	 *
	 *  タスク例外処理ルーチン内での空ループの回数（tex_loop）は，
	 *  task_loopの4分の1の値（空ループの実行時間が0.1秒になるループ回
	 *  数）に設定する．
