Well, there are several cases where we 'forget' about
shared area's. One of them is where SysV shared memory
is unmapped from all processes but the handle remains.
Since we do page scanning by process, we can't find
such an area. I don't know if this has been fixed by
now, but I certainly remember the messages about it...

OK, I'll do that.

"To teach is to learn twice" I'm not a very productive
programmer yet, I don't even do a CS study. By writing
docs, I get to think about things more and as a result
I am becoming a better programmer.
Also, I really like it when people can actually use
the code we're writing. We don't _just_ write it for
fun...
Rik.
