> There are a number of portability problems with python on win32 as I've learned over the past few days.  
>   * Our use of multiprocess is broken in cqlsh for windows.  
> https://docs.python.org/2/library/multiprocessing.html#multiprocessing-programming
> The code was passing self to the sub-process which on windows must be pickleable (it's not).  So I refactored to be a class which is initialized in the parent.
> Also, when the windows process starts it needs to load our cqlsh as a module. So I moved cqlsh -> cqlsh.py and added a tiny wrapper for bin/cqlsh 
>   * Our use of strftime is broken on windows
> The default timezone information %z in strftime isn't valid on windows.  I added code to the date format parser in C* to support windows timezone labels.
>   * We have a number of file access issues in dtest
>   * csv import/export is broken on windows and requires all file be opened with mode 'wb' or 'rb'
>

>   * CCM's use of popen required the univeral_newline=True flag to work on windows
