   Hi @szha, thanks for the feedback. I'm not sure if I completely understood though.
   If the user wanted the memory to be freed right away couldn't they use a non-pooled storage manager (i.e. storage::NaiveStorageManager<storage::GPUDeviceStorage>()) or did you have something else in mind? (Although currently there is no value for MXNET_GPU_MEM_POOL_TYPE that would do this)
   
   At least for my use case I was hoping to still use the memory pool/caching (for performance) but periodically pause and release the memory (so another process could use the gpu memory). I understand the release_all call could be expensive but it would not/should not be called regularly so overall it seems like it would effect performance less than using non pooled memory.
