Are you trying to say that any kind of significant portion of QEMU 
users have clustered file-systems?

I think that's unlikely, and it'd be nice if QEMU by default did a 
fcntl() on writeable image files to lock itself from multiple access, 
that'd benefit the vast majority of users.

Let the 0.x% of users who need to run with weird/esoteric fses cope..
