If a GenArrayWaitHandle is imported, the current implementation imports only the active child. Try to import other children as well to increase parallelism. enterContext() can throw an exception if a cross-context dependency cycle is found. It is safe to ignore such exception when importing non-active children. The import will be attempted and fail again once onBlocked() reaches the dependency that causes the cycle.
