Really great.

We do potentially-vast gobs of waiting for I/O in
prune_icache->dispose_list->truncate_inode_pages().

But then, why would dispose_list() run truncate_inode_pages()?  Reclaiming
an inode which has no links to it, perhaps - it's been a while since I was
in there <wishes he added more comments last time he understood that stuff>

clear_inode() does wait_on_inode()...
