Something's wrong with accept()

[Adam]

On the recent -current [1], something is wrong with accept(). This Python 
script fails:

```
import socket

socket_path = "/tmp/my_unix_socket"
server = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
server.bind(socket_path)
server.listen(5)
connection, client_address = server.accept()
```

with "OSError: [Errno 14] Bad address".

Now it is not possible to build Firefox, because its Python script goes into an 
infinite loop, and ktrace shows calls to 'paccept'.

Please, help.

[1] I've built one today. My previous build was about a week old and the 
problem didn't occur.
