Hmm.. I think you're right. A straightforward implementation would
not necessarily fix this.
An additional requirement that an inode can not be freed and then
allocated in the same segment should be sufficient, though.
It may not do nice things to the performance of create/unlink-heavy
things like mail queues, though. (Actually, doesn't ext2 already
have code to make it prefer to allocate inodes which weren't freed
recently, anyway?)
