When resuming from a writeable filesystem, the filesystem has to match the
contents of suspended memory. If you've TOUCHED the filesystem since
suspending, the resume is going to shred it, cross-link the heck out of it,
and generally be evil. (There are open filehandles saved in there, page
table entries to maped stuff... Just don't go there.)
