A process may pause for garbage collection, lose contact with the coordinator, stall under scheduler pressure, or resume after a machine suspension. The lock service can correctly grant the lease to another worker while the old worker still has unfinished work.</p> <p>That gap matters when both workers can reach the protected resource. A lease controls ownership in the coordinator; it does not automatically revoke a delayed database connection, storage request, or RPC that was prepared by the previous holder.</p>
