Re: [libvirt] [PATCH] Make virInitialize thread safe

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; Currently there is a restriction that multi-threaded applications must manually call virInitialize, before threads start using libvirt, because it is not thread-safe. By switching it to use a virOnceControl initializer we gain thread safety, and thus applications no longer need to manually call it. They can rely on virConnectOpen invoking it for them.
