Aside from some unix variations that basically didn't do restart at all there have always been problems with signal restart semantics. For sockets and various devices (raw ttys, I think) you could definitely lose data.

Sockets? Are you sure? I find it unlikely that such a severe problem could persist in many Unix variants for so long. I've never heard of any mention of such a thing.
