Hmmmm, is this right?

For event, the listening socket, and hence the accepted socket, is 
always set to non-blocking in the MPM.

For non-event on Unix, the listening socket, and hence the accepted 
socket, is set to non-blocking IFF there are multiple listeners.

So that line is not redundant in the non-event, single listener 
configuration on Unix... no?
