[libvirt] In libxl_driver, how to lock/unlock objects while doing an operation that runs for a long time?

In the discussion : http://thread.gmane.org/gmane.comp.emulators.libvirt/53534 People mentioned about long-term operations' LOCKs there. It seems that, in libxl_driver, certain opeations may hold a lock for too long, thus other operations, even those just do query jobs, would be blocked.
