 For maximum performance, it is expected that the users would re-implement an equivalent to the runtime library which suits better their needs (With a more clever multi-threading strategy, load-balancing between NEON and OpenCL, etc.)
 
+@section S4_1_2 Thread-safety
+
+Although the library supports multi-threading during workload dispatch, thus parallelizing the execution of the workload at multiple threads, the current runtime module implementation is not thread-safe in the sense of executing different functions from separate threads.
+This lies to the fact that the provided scheduling mechanism wasn't designed with thread-safety in mind.
+As it is true with the rest of the runtime library a custom scheduling mechanism can be re-implemented to account for thread-safety if needed and be injected as the library's default scheduler.
