   For ThreadedEngine, I read the source code just now and believe that it is thread-safe. The Push API consists of 3 parts: bulk-related; dependency; PushToExecute. Bulk-related part is thread-local, so safe; The dependency and PushToExecute parts are designed to be thread-safe. Therefore, in conclusion I believe the ThreadedEngine is thread-safe.
   
   I am not sure why our document says "Push APIs are not thread-safe" (https://mxnet.incubator.apache.org/architecture/overview.html). @tqchen Could you help confirm this?
