Twisted is doing this for the process writer doRead operation:

def doRead(self): """The only way this pipe can become readable is at EOF, because the child has closed it. """ fd = self.fd r, w, x = select.select([fd], [fd], [], 0) if r and w: return CONNECTION_LOST

One more separate issue unrelated to the poll sematics: why is the above using select? I'm using the process protocol on the server side too, and I used ulimit -n 40000 on the server side. The above will break badly if I'll ever reach > 1024 connection simultaneously. Overall I hope the above code never has to trigger, why isn't it using the pollreactor anyway? Is it dead code or what?
