some questions about PooledPredictor

[lazylazypig]

Hi,
when i read the source code of PooledPredictor, in the function PooledPredictor::startPredictorThread, i noticed a commit about GPU mode:
// We tried adding weight sharing between nets on the same GPU,
// which resulted in sporadic NaN outputs of cuDNN (R5) layers.
// Removing weight sharing immediately solved this problem.
it looks like we cannot share trained layers at the GPU mode with cuDNN. Does this problem solved now, when i use cuDNN v5.1?
thanks
