Its a rule of thumb -- and it seems I got it wrong. You need string.h
for things like memcpy(), which of course it not a performance problem.
Its really the use of str* functions that tells you you have a
potential performance problem. So I'll go back to my old heuristic
which says if you call strlen(), then you have thrown performance out
the window.
