Call Targets Not Optimized

[Cristian Esquivias]

Nah, I meant just for manual testing. Off the bat, contorting my code for
the benchmark felt like that would give me skewed results, but then I
realized I can just stick my main function in an infinite loop and it
shouldn't be so bad. I'll fiddle with the flags just in case that suits my
needs. If I ever need something more robust I'll be sure to ask.

Thanks,
Cristian
