Summary: CGIHTTPServer execfile should save cwd 

Initial Comment:
In CGIHTTPServer when running a script via execfile the 
cwd is not saved and restored.  If the executed script 
changes the cwd subsequent requests will fail because 
self.translate_path in SimpleHTTPServer relies on the 
cwd.

One fix is to suround the execfile call with
save_cwd = os.getcwd()
and
os.chdir(save_cwd)

Here is the proposed fix starting at line 254:

+	save_cwd = os.getcwd()
	try:
	    try:
	        sys.argv = [scriptfile]
	        if '=' not in decoded_query:
	            sys.argv.append(decoded_query)
	        sys.stdout = self.wfile
	        sys.stdin = self.rfile
	        execfile(scriptfile, {"__name__": 
"__main__"})
	    finally:
+	os.chdir(save_cwd)

It looks like a bug worth fixing, and the proposed patch seems reasonable.

Since a patch is in the comments I am making this a patch instead of a bug.

As for the idea, it seems good to me.  Anyone else care to comment?

Here is the (hopefully) properly indented fix:

+   save_cwd = os.getcwd()
    try:
        try:
            sys.argv = [scriptfile]
            if '=' not in decoded_query:
                sys.argv.append(decoded_query)
            sys.stdout = self.wfile
            sys.stdin = self.rfile
            execfile(scriptfile, {"__name__": "__main__"})
        finally:
+           os.chdir(save_cwd)
