#1517: numpy.load does not release file handle for npz files

 Reporter:  etecman           |       Owner:  somebody
     Type:  defect            |      Status:  new     
 Priority:  normal            |   Milestone:  2.0.0   
Component:  numpy.lib         |     Version:  1.3.0   
 Keywords:  load, filehandle  |  
------------------------------+---------------------------------------------
 When opening a npz file with numpy.load, the handle to the file is not
 released such that the file cannot be deleted during the runtime of the
 script - even if all returned values are deleted.

 Error message:

 WindowsError: [Error 32] The process cannot access the file because it is
 being used by another process: 'deleteme.npz'

 Example:

 {{{
 import os
 import numpy
 a =  numpy.array([[1, 2, 3], [4, 5, 6]])
 filenameNPZ = "deleteme.npz"
 numpy.savez(filenameNPZ, a = a)
 npz = numpy.load(filenameNPZ)
 del npz
 os.remove(filenameNPZ)
 }}}
