You do not need to call pthread_testcancel(): rt_task_shadow sets the
thread cancellation type to PTHREAD_CANCEL_ASYNCHRONOUS, which means
that pthread_cancel will send a signal to this thread to terminate
it. So, the reason for the deadlock is probably elsewhere. Could you
reduce your application to a small self-contained test which wouls show
us what you are observing ?
