Using UpdateSystemActivity (TotalAct) is deprecated in OSX 10.8.

The recommended approach is now to block it with the following call:

 IOPMAssertionCreateWithName(kIOPMAssertionTypePreventUserIdleDisplaySleep, kIOPMAssertionLevelOn, reasonForActivity, &assertionID);

I just decided it and forgot to post it as an answer. Call UpdateSystemActivity(OverallAct) every 30 seconds.
