Without synchronization, tx_work can race with socket and\ndevice teardown when a process is killed (e.g. by SIGKILL), leading\nto use-after-free or leaked references.\n\nSet SEND_SHUTDOWN first so that if tx_work is already running it will\nsee the flag and skip transmitting, then use cancel_work_sync to wait\nfor any in-progress execution to finish, and finally purge any\nremaining queued
