   one more data point I've gathered is that if I remove the logic of using the shared memory (a.k.a the [global _worker_dataset](https://github.com/apache/incubator-mxnet/blame/master/python/mxnet/gluon/data/dataloader.py#L421)), it also resolves the memory leak issue. Most like the multiprocess + shared memory implementation is left behind some staled references, which are holding the gpu memory with the latest Cuda implementation.
