Obviously it was a recursive lock before. Now pthread_rwlock_wrlock() 
must not be called twice by the same thread. I am fine with the 
conversion below per se. The functions below are quite low-level now 
(close to virsh) that they are not called recursively. So from this 
perspective for this patch:
