Author: gregory.p.smith Date: Tue Sep 30 22:41:13 2008 New Revision: 66703 Log: Works around issue3863: freebsd4/5/6 and os2emx are known to have OS bugs when calling fork() from a child thread. This disables that unit test (with a note printed to stderr) on those platforms. A caveat about buggy platforms is added to the os.fork documentation.
