Well, I'll back out it for now, but we need to fix the kernel to handle it properly. > It also bzeros a multiple of 6 * FDSETSIZE bits. This will take a > fairly long time with a large FD_SETSIZE.

It means that current select algorithm must be rewritten, any ideas? -- Andrey A. Chernov <ache@null.net> http://www.nagual.ru/~ache/
