AFAIK Linux is the only one. If we want to stay portable we need to use

handled this way. Thats the safest.

Actually, I don't think we need to stay portable though.
The JDK docs say: "Some non-standard implmentation of this method may
ignore the specified timeout."

So.. Presumably, Solaris supports it too. But we don't need to though. Anyway, this is still better than before when it didn't work at all :)

on older (2.4 or older) Linuxes it will be broken.

Well, it will still be broken an most if not all non-Linux Unices. Even

For what it's worth, Mac OS X 10.4.6's man page for `setsockopt' claims to support this. But using select is ultimately better, and even better than that is using epoll or kqueue where available.
