I Noted it re-enabled metalayer cralwer. I had it disabled before update. The premise of constantly scanning MMC for new files seems wrong to me. Unless they build a safeguard (to only do so when plugged in, or for some amount of time, or to run a fdsk before operating) I don't see how it would not remain a problem.

*another report below says this isn't true, I do dual boot and might not have had it disabled on the system memory*
