[pypy-svn] r78006 - pypy/branch/fast-forward/pypy/module/imp

New Revision: 78006

Modified:
   pypy/branch/fast-forward/pypy/module/imp/__init__.py
Log:
Grab and release the import lock when forking the interpreter.

I could not find any test for this change, but:
- CPython 2.7 has similar code
- when translated, it helps a lot test_multiprocessing, which did not even start a single test before.
