Subject: [PATCH] Issue #112: Prepare Stackless 3.5, fix a C-Python test suite
 bug

This commit merges the fix from C-Python pull request
https://github.com/python/cpython/pull/1066 (git commit 22e032a2e) for
bpo-30028. Without this change
   $ ./python -m test.regrtest test_multiprocessing_fork
fails. ($ ./python -m test.test_multiprocessing_fork is OK.)
