#1809: Memmap with multiprocessing in Windows

 Reporter:  tfmoraes         |       Owner:  somebody   
     Type:  defect           |      Status:  new        
 Priority:  normal           |   Milestone:  Unscheduled
Component:  numpy.core       |     Version:  1.5.1      
 Keywords:  memmap, windows  |  
-----------------------------+----------------------------------------------
 Running the following code https://gist.github.com/929168 in Windows (I've
 tested only in XP) a AttributeError exception happens, here a more
 detailed traceback https://gist.github.com/944144 .

 That code creates a new python process via multiprocessing to run a
 function, the parameter to this function is a memmap array created by the
 main process. This code works with the last numpy stable version in Linux
 and Mac OS X, but in Windows. Numpy version 1.4.1 runs correctly that code
 in Windows, Linux and Mac OS X.
