Yes this is what I am suggesting. However I have another idea for a general purpose solution. The only time you want a timeout in a select/poll/epoll is if you have On Wednesday, December 11, 2013 7:00 AM, lars van Gemerden <[email protected]> wrote: Hi Andrew, It wasn't blocked on IO, the server got stuck in it's mainloop (or similar name).
