// Synchronize main handler for tests
//
// NOTE: This mechanism works ONLY when it is known that a single unit
// of execution under test does not spawn or otherwise extend entries
// into the main loop execution queue.
//
// If the execution under test reposts additional execution units to
// the main loop queue then this synchronization mechanism is unreliable
// and alternative methods must be used to properly sync within the
// multithreaded environment.
