Make it possible to run test_subprocess.py with Python 2.2, which lacks test_support.reap_children().

Change error message to indicate that VS2003 is necessary to build extension modules, not the .NET SDK.

The hppa ubuntu box sometimes hangs forever in these tests.  My guess
is that the wait is failing for some reason.  Use WNOHANG, so we won't
wait until the buildbot kills the test suite.

I haven't been able to reproduce the failure, so I'm not sure if
this will help or not.  Hopefully, this change will cause the test
to fail, rather than hang.  That will be better since we will get
the rest of the test results.  It may also help us debug the real problem.

*** The reason this originally failed was because there were many
zombie children outstanding before rev 47158 cleaned them up.
There are still hangs in test_subprocess that need to be addressed,
but that will take more work.  This should close some holes.
