I think it must be done as a workaround _only_. What's the point of having asynchronous I/O capability for relatively fast HDDs while missing this support for other (slow) I/O such as ttys or pipes? This situation renders the whole presence of aio almost useless. Sincerely, Dmitry -- Atlantis ISP, System Administrator e-mail: dmitry@atlantis.dp.ua nic-hdl: LYNX-RIPE
