Automated batching of fast tasks into longer running jobs to hide multiprocessing dispatching overhead when possible.

FIX compressed pickles interoperability between Python 2 and Python 3. Compressed pickles can be written with one and read with the other.

FIX make it possible to call joblib.load(filename, mmap_mode='r') on pickled objects that include a mix of arrays of both memmory memmapable dtypes and object dtype.

FIX #146: Heisen test failure caused by thread-unsafe Python lists
This fix uses a queue.Queue datastructure in the failing test. This datastructure is thread-safe thanks to an internal Lock. This Lock instance not picklable hence cause the picklability check of delayed to check fail.
When using the threading backend, picklability is no longer required, hence this PRs give the user the ability to disable it on a case by case basis.

BUG: use mmap_mode=’r’ by default in Parallel and MemmapingPool
