Summary: CGIHTTPServer fix

Initial Comment:
Here's a fix for the CGI server. The problem only
occurs on systems that support os.fork(). When you
invoke a CGI script with a query string and then
subsequent invoke it without a query string (or with an
empty query string), the second invocation gets passed
the query string of the first invocation. This is
because of the way os.environ is updated in the parent,
but when there is no query string, the old query string
doesn't get deleted. The solution is to update the
os.environ in the child.

The first part of the patch makes sense to me.
The second part updates os.environ which is shared between 
successive calls.  I would have expected something like:

   childenv = os.environ.copy()
   childenv.update(env)
    . . .
   os.execve(scriptfile, args, childenv)
