Not only accidental untar, but buggy progs as well. Recently, I found out that named had created tens of thousands of (luckily zero-length) files in a single dir on ext2. While it only took couple of hours to delete them with "find . -name '...'| xargs -n 5000 rm" commands, I can imagine remote DOS attacks through daemons that create local temp files. Accessing such directory quickly becomes slow as molasses on ext2.
Daniels patch seems great. I also recall someone (Ted T'so? Stephen Tweedie?) had another dir access speed-up patch for ext3... Is that applicable to ext2 or was it already merged?
