Libvirt stores pid of domain(e.g Qemu) process when a domain process is started and same pid is used while destroying domain process. There is always a race possible that before libvirt tries to kill domain process, actual domain process is already dead and same pid is used for another process. In that case libvirt may kill an innocent process. With this patch we store start time of domain process when domain is started and we match stime again while killing domain process if it does not match we can assume domain process is already dead. This patch series tries to create a generic interface which can be used for non-domain processes too, even though initial patch series handles re-use of domain process only.
