util.poll: Increase max epoll events per call This makes the struct roughly the same size in both epoll and select mode (64bit). There doesn’t seem to be much guidance on an appropriate size, it does not seem to matter too much since if there are more events they will simply show up in the next epoll_wait call. The number of exactly concurrent events should be fairly low most of the time anyways.
