// A pool for managing free/used tab sync nodes for the *local* session.
// Performs lazy creation of sync nodes when necessary.
// Note: We make use of the following "id's"
// - a tab_id: created by session service, unique to this client
// - a tab_node_id: the id for a particular sync tab node. This is used
//   to generate the sync tab node tag through:
//       tab_tag = StringPrintf("%s %d", local_session_tag, tab_node_id);
//
// A sync node can be in one of the two states:
// 1. Associated   : Sync node is used and associated with a tab.
// 2. Free         : Sync node is unused.
