After seeing this I decided to take a look at a box I recently put
2.4.13+ext3(-pre6 + manually fixed .rej) and I got this:

        total:    used:    free:  shared: buffers:  cached:
Mem:  125820928 121167872  4653056        0 295002112
18446744073458835456
Swap: 536117248  4866048 531251200
MemTotal:       122872 kB
MemFree:          4544 kB
MemShared:           0 kB
Buffers:        288088 kB
Cached:       18446744073709305672 kB
SwapCached:       1104 kB
Active:          28832 kB
Inactive:        14416 kB
HighTotal:           0 kB
HighFree:            0 kB
LowTotal:       122872 kB
LowFree:          4544 kB
SwapTotal:      523552 kB
SwapFree:       518800 kB

I only have 1 ext3 filesystem yet, because I was stress-testing the box
before I put it into real use.

/dev/sdb2     ext3     16G   33M   16G   1% /mnt/tmp

This box is a 167Mhz Ultra 1, 128M memory 512M swap. I ran bonnie++ on
the ext3 partition for about 15 hours and then let it sit idle for about
the same before I noticed this.
