I don't see that option anywhere on my K-menu, either top level or
further down in any likely spot (system, utilities, control center).
I think I remember seeing it somewhere (on the kdm greeter?) and
wondering what it did.
Oh... maybe this only appears if you have a reserve session possible.
I may have seen it when I had one, and now it's gone because I removed
the reserve word since I couldn't make it work.

But there is no such file. Or are you saying that to start session 1
I should send this to xdmctl-:0?

Correct. Since, as written, it appears you must send the "reserve"
command to the corresponding FIFO.

The fact that a bug report does not include a fix does not mean there
is no bug. Short of a patch, I suggest the document should explain
how to make reserve work.
This would involve several elements:
1. How to get the "start a session" to appear on your menu. I don't
know how.
2. Stating that to activate a reserve session you should invoke start
a session and then send the "reserve" command to the corresponding
FIFO (I'm assuming that's the correct method).
3. (Optional) Explain a pure FIFO way to achieve the effect of start a
sessio without getting the GUI involved. (I suspect there is such a
method, but I don't know it.)
At any rate, the missing piece of the puzzle for me seems to be how to
invoke the "start session" function, or how to get it on my menu.

'seem' referred to the fact there might be some way to make it work,
as there seems to be. But even if there is, the documentation needs
to explain it, so it's a documentation bug.
When I get to a good point to tweak my Xservers and kill all my
sessions I'll give this all a try.
