Yeap, that is what is happening.  We've seen it happen here at BSDI
even and looked at it to make sure something else wasn't going on.
I think that apache is probably over doing the wake-up every second
thing and when I get some time I'll probably submit a patch (unless
someone else does it in the meantime) but since it isn't hurting
anything that all it's not really worth messing with too much :-)
