I am just giving it a try, but I noticed that the epoll multiplexer didn't
work out of the box. The reason appears to be that I am using a 2.6.8 kernel
here (I don't have any choice) and this kernel returns EFAULT when trying to
do an EPOLL_CTL_DEL with the event ptr == NULL. The workaround is quite
trivial to pass a dummy event in EpollFDMultiplexer::removeFD:

  struct epoll_event eevent;
  eevent.events = 0;
  eevent.data.u64 = 0;

  if(epoll_ctl(d_epollfd, EPOLL_CTL_DEL, fd, &eevent) < 0)

bye, Christof
