1. A method comprising: determining whether a first task originated from a first node in a network of nodes; responsive to a determination that the first task did not originate from the first node in the network of nodes, determining, by a second node in the network of nodes, whether a first timestamp for the first task is prior in time to a second timestamp for a second task originating from the first node and previously executed by the second node; responsive to determining that the first timestamp for the first task is prior in time to the second timestamp for the second task, determining that the first task is stable at the second node with respect to the first node; and responsive to determining that the first task is stable at the second node with respect to the first node, executing, by the second node, the first task.
