My first approach would be this: Create a condition variable and a mutex,
start all threads giving them the condition var and mutex, wait on the
condition var in the main thread. In all threads if the value is
retrieved signal the condition var. In the main thread kill all non
terminated threads (or simply let them run) and proceed.
