roxlu: the usual way is to create a pipe() (or eventfd()) and add it to the list of fds given to poll()
then you can write() on the fd, which will wake up poll()
hey  thanks pinchartl! I just implemented a solution using eventfd()
I don't fully understand how it's supposed to work, but it works. What I'm not sure about is if you have to read/write to the eventfd again to reset it's value. 
if you start expanding the event handlign plumbing, I recommend looking at libevent
yeah :) 
way back when I looked into libevent (and when I was less experienced) I thought that libevent made it impossible to do zero-copy
but I could have beeen wrong then
