Does it check the return value? I suspect it doesn't ;-)
To explain, because valgrind reserves some file descriptors for itself
at the top end of the range it also refuses attempts to change the limit
because to do so it would have to move it's own descriptors.
So you should find that the setrlimit call returns EPERM if you try and
change the hard limit when under valgrind.
