 * \brief Thread group
 *
 * Thread group manages collection of threads that are expected to be
 * launched simultaneously as a group.
 *
 * Shared barrier is provided for synchronizing execution. Terminating thread
 * early either by returning from ThreadGroupThread::runThread() or throwing
 * an exception is safe, and other threads will continue execution. The
 * thread that has been terminated is simply removed from the synchronization
 * group.
 *
 * TestException-based exceptions are collected and translated into a
 * tcu::TestStatus by using tcu::ResultCollector.
 *
 * Use cases for ThreadGroup include for example testing thread-safety of
 * certain API operations by poking API simultaneously from multiple
 * threads.
