Why does my Android Service sleep when the phone is inactive.

During my development of an Android app for reporting periodic wifi scans, I encountered that the android service responsible for reporting the wifi-scans halted when the phone went inactive.

I searched Google and found this newsgroup thread, which gave me the answer to my problem.
