Hi,

I have a plpython stored procedure which sometimes fails when I run my
applications automated test suite. The procedure is called hundreds of
times during the tests but only fails a few times, often with the
following ImportError:

    Traceback (most recent call last):
      File "/Users/jinty/.buildout/eggs/setuptools-0.6c11-py2.7.egg/site.py", line 73, in <module>
        __boot()
      File "/Users/jinty/.buildout/eggs/setuptools-0.6c11-py2.7.egg/site.py", line 2, in __boot
        import sys, imp, os, os.path
      File "/Users/jinty/src/mp/lib/python2.7/os.py", line 49, in <module>
        import posixpath as path
      File "/Users/jinty/src/mp/lib/python2.7/posixpath.py", line 15, in <module>
        import stat
    ImportError: No module named stat

Changing the order in which the tests are run, or running tests
individually makes the error move/change or disappear. The behaviour is
the same with PostgreSQL versions 9.2.2 and 9.1.7.

I have tried (but failed) to reproduce this error in a simple .sql
script. Outside of the tests, it always seems to work.

Having run into a brick wall debugging this, I'm hoping there's someone
here who can help?
