It may happen that, for instance after daemon restart, that one thread is still in qemuProcessReconnect(), i.e. filling in runtime information by talking to QEMU on monitor. If another thread then tries to format domain XML (which is currently guarded by plain mutex on virDomainObj) it'll produce incomplete and misleading information (e.g. current size of virtio-mem). This happens because the reconnecting thread talks to QEMU on monitor and thus unlocks the domain object frequently allowing the XML formatting thread to acquire the mutex meanwhile.
