I don't have multiple threads or anything like that, and I thought select() was non-blocking, however, as I add more items to an array used as the IO object, and using select(), after about 1000~ items in the array (with some interaction on them).. the whole script exits with a deadlock / fatal error...

Hope any1 could help Thank you so much!
