Test code:
import os
from select import select
fp=os.open("foo.txt",os.O_WRONLY|os.O_CREAT)
select([fp],[],[],0)
running with jython 2.5b1 results in:
Traceback (most recent call last):

This is expected behaviour.
On java, and thus on jython, *only* sockets can be selected upon.
Files *cannot* be selected upon, because the FileChannels underlying
"file descriptors" on jython do not subclass
java.nio.channels.SelectableChannel.
I have updated the documentation on the select module wiki page to make
this more explicitly clear.
