I really think this patch can be useful, in my own case when testing
debian-installer (I already cache=writeback). In short all that is about
developing and testing, as opposed to run a VM in production, can
benefit about that. This was one of the original use case of QEMU before
KVM arrived.

Unless someone can convince me not to do it, I seriously considering
applying this patch.

There really needs to be an indication in the --help output of what the ramifications of this option are, in the very least. It should also be removable via a ./configure option because no sane distribution should enable this for end users.
