Yes, that should do it. Note that this is compile time vs runtime checking 
(the kernel the code runs under could possibly not understand this syscall), 
but the code doesn't to any harmful if both calls fail so its only a 
theoretical problem.

Help with what? Finishing the index? No. Perhaps a general idle detection 
would be better (does it have a X11 connection? if the screensaver is running 
or the user is idle then switching to fulll speed is probably a good idea).
