It returns "Bad file number". Doing some debug i've found that the 
problem is not in select. The situation is:

- I have two tasks, one for sending data and the other for receiving.
- At some point the 'writing task' sends a packet, and then sends a 
'FIN-ACK' packet, without returning error, or close() being called.

Any idea?
