(Almost) everything mmap()s /lib/libc.so.6. That's probably more important
if even read-only mappings of deleted files prevent remounting ro. (this
requirement makes sense, because you have to leave the FS with the file
deleted and the blocks freed, so nothing would be left to back the mapping.
The only way to support this would be ugly hacks, I think.)
