But mmap() *is* supported on this object. It's just that PROT_WRITE isn't
supported, in conjunction with MAP_SHARED. Perhaps we should return ENOTSUP for
a PROT_WRITE shared mapping?

And whatever POSIX says, this is a common behaviour from file systems and it's
easy to work cope with. Why *wouldn't* we?
