idled and ftp processes

[Keyser Soze <mkultra_(_at_)_dqc_(_dot_)_org>]

I have idled setup to limit simultaneous user sessions to 3.
When people ftp, and disconnect, a utmp entry lingers around for a very
long time. Most of the time they do not go away. This confuses idled and
thinks that they are logged in, so if 3 ftp utmps are "hung" the user
cannot log in. Idled attempts to terminate the ftp session, but fails (and
keeps trying). Is there a way to tell idled to ignore sessions that are on
ftp* ? Or is there a fix in OpenBSD to correctly delete the utmp entries
for ghost ftp sessions?

Thanks in advance...

Here are the logs form /var/log/idled.log
