fc6fcf23f7 Lock the cudaFree mutex. (#880) 
Prevents NCCL calls from overlapping with cudaFree() which can lead to
deadlocks.

bd5303010d Refactor autograd package to separate Python dependencies. (#662) 
The core autograd Variable, Function, and Engine no longer depend on the
Python API. This let's us implement functions in C++. In the future, we
can also multithread engine and release the GIL for most of the
non-Python backwards.

24af02154c Use ForkingPickler for sharing tensor/storages across processes (#344) 
This hooks into the (internal) ForkingPickler class in multiprocessing
to reduce tensors, storages, and CUDA events instead of our queue from
joblib. This makes it easier to use the standard multiprocessing classes
in later versions of Python.

This also exposes:

 - Tensor/Storage.share_memory_()
 - Module.share_memory()

These methods move the CPU tensors and storages to shared memory. If
you're using the "fork" method of multiprocessing, these objects can be
directly inherited instead of serialized through a queue.

f2d7e94948 Use torch.Size for Tensor sizes and tuple for strides 
See issue #20

The torch.Size class is a tuple subclass which distinguishes sizes from
other tuples so that torch.Tensor(size) is interpreted as size instead
of data.

multi-gpu training when using 4+ Maxwell GPUs.
