can this issue still be reproduced in recent versions of the packaged
numpy?

Title:
  import numpy fails after Py_Finalize in embedded python

Status in “python-numpy” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: python-numpy

  I am writing an application that embeds python and invokes scripts
  that import numpy. I have found that while numpy will import correctly
  the first time, if I run Py_Finalize()  and then reinitialize the
  python interpreter, the second time numpy is imported I get this
  error:

  Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/usr/local/lib/rtxi/rtxilib.py", line 3, in <module>
      from numpy import ndarray, array, empty
    File "/usr/lib/python2.5/site-packages/numpy/__init__.py", line 36, in <module>
      import core
    File "/usr/lib/python2.5/site-packages/numpy/core/__init__.py", line 5, in <module>
      import multiarray
  SystemError: dynamic module not initialized properly

  The workaround is to simply skip the call to Py_Finalize(). This problem was discussed on the scipy mailing list previously:
  http://projects.scipy.org/pipermail/numpy-discussion/2007-April.txt.gz
