    debugging: labs: remove dubious sentence

 actually taking a negligible time. However, valgrind simulate the program with
 an "ideal" cache. In real life, the processor is often used by other
 applications and the kernel also takes some time to execute which leads to cache
-disturbance. Hence, callgrind is a good tool to optimize applications based on
-CPU time
