    qemubuilder: low read/write performance on qemu block devices (closes: #600056)

    (which is fine even for lenny).

    qemubuilder: low read/write performance on qemu block devices (closes: #600056)
    
    By default, qemu uses writethrough caching, which is more reliable in
    case the host crashes, but less performant.
