[libvirt] [PATCH python] Release the GIL during virDomainGetMemoryStats
We discovered that the entire python process get stuck for about 30
seconds when calling virDomain.getMemoryStats() if libvirt is stuck in
virConnect.getAllDomainStats() on inaccessible storage. This blocking
cause a horrible mess in oVirt.
This patches adds the standard *_ALLOW_THREADS around the call to avoid
this unwanted blocking.
