Dmitry Tantsur 2b8cc3a93f Lock nodes to avoid simultaneous introspection requests ... Now a NodeInfo object has a lock instance attached, which is associated with a node UUID. New calls acquire_lock and release_lock are added. NodeInfo.find_node now always acquire a lock, get_node does it optionally. NodeInfo.finished now always release a lock. Note that this change does not make NodeInfo thread-safe. Rather it's preventing simultaneous operations on the same node.
