Missed to reply to list as well, sorry.

If you mean my patch it is of course rock solid(tm) ... Well at least 
it works for me. :-)                                                  
I has not been through any kind of formal testing but a have run a    
large number                                                          
of stress tests and tested a very large distributed application with  
it ...                                                                
                                                                      
For the other poll extensions:                                        
1) Solaris /dev/poll was introduces as a patch for Solaris 7 and is   
official since                                                        
    Solarais 8.                                                       
2) /dev/epoll is still being developed by Davide. I will most likely  
change somewhat                                                       
    with more ioctl. It is unlikely that the semantics of EP_POLL will
change.                                                               
3) I don't have FreeBSD running anywhere and deliberately skipped     
this.
