Agreed, it's unclear. In Python trunk the paragraph reads:
If *close_fds* is true, all file descriptors except :const:`0`, :const:`1` and
:const:`2` will be closed before the child process is executed. (Unix only).
Or, on Windows, if *close_fds* is true then no handles will be inherited by the
child process. Note that on Windows, you cannot set *close_fds* to true and
also redirect the standard handles by setting *stdin*, *stdout* or *stderr*.
but doesn't mention throwing exceptions in older versions.

Yes, the tests run now against the latest svn binary I have, and pass
(except for some failures unrelated to your patch). I'll try and test the
patch against HEAD this week, if no one beats me to it.
