uhm, and why do you think utempter is the preferred choice?
last time i checked, nobody was shipping konsole setgid utmp. with kdeinit, that's not even an option.

there are several options how to deal with this:
- fork()/wait() around the utempter calls, so it can't mess with the signal handling of the current process. though i seem to remmber that the addToUtmp() call actually uses the PID
- re-implement the libutempter calls with QProcess. that's actually how it was originally, but was changed because there were incompatible versions of utempter - but that seems like a minor concern compared to the status quo.
- drop utmp handling altogether, as it's been mostly superseded, first by consolekit, and now logind. however, respective bindings would have to be actually implemented, and i have no clue how things are supposed to be done. just some dbus calls?
-- what about non-linux systems?
