Each time an extent handle is opened and closed, if the inode has an extent tree which does not fit in the inode's i_block structure, a filesystem block buffer was not getting released. Since e2fsck opens an extent handle for every inode using extents, this can translate to a very large amount of memory getting lost. Thanks to Henrik 'Mauritz' Johnson for discovering and pointing out this leak, which he ran into while running the "rdump" command in debugfs.
