From cimtest, Calling to virEventRegisterDefaultImpl() of libvirt API, resulting random fail in cases, which seems most likely tog-pegasus's internal data is damaged. The root cause may be: 1 libvirt event API have a bug, we called it from thread A and then do other things in thread B, maybe it did not handle this well. 2 tog-pegasus have confilict with libvirt's event. 3 Potential requirement in libvirt event API or tog-pegasus's thread, which is not document so we used them in a wrong way. Most possible is that tog-pegasus tries to manage all threads resulting the error. This patch bring back libvirt-cim's own old event implemention, which is by default used now. CSI from libvirt can still be activated with a macro. This patch also have changed some buglike code of old libvirt-cim's event implemention. Tested with cimtest on following Env, no more strange error found: RH6.3 libvirt-0.9.10-21.el6.x86_64 tog-pegasus-2.11.0-3.el6.x86_64 Note that to make review easy, this patch try move the code as little as possible, a following "clean up" patch will move the code together.
