Hello all, 

The official doc describes `Pool.map(func, iterable[, chunksize])` as "A parallel equivalent of the map() built-in function.". 

Since the function signature of `map` is `map(function, iterable, ...)`, I hereby suggest that `Pool.map` should change its function signature to `Pool.map(function, iterable, ... [, chunksize])`. This will bring true equivalent to these functions. 

Tell me what you think.
