Hm - I have it turned off on my Touch. I watched it go to screensaver and I'm not sure what to look for? I see 'wifid: spectator: scan start' What is the indexer called? As you can see, I have VERY little knowlege of this stuff!
Edit - I deleted the indexes, watched it go into screensaver, and saw it start the indexer. FAIL!! Oh well, I guess this was all just a waste of time - again. Although, I did learn a bit
Edit 2: it didn't create the files I had deleted, it just failed. Maybe if the script does a tar.gz of the directory first, then delete/restore at will? (I did, of course have them backed up before I deleted, so I can restore if I want.)
