On Linux, I noticed that in root X logins, two utmp entries are
created for each xterm terminal line, one of which is left as a stale
entry after logout. An xterm process trace revealed that xterm
invokes utempter at startup to add the utmp record, yet also adds its
own record (i.e. with a different id). At exit, utempter is invoked
to remove the entry it added, but the xterm-added entry is left in the
file.
This appears to be a bug which was fixed in xterm patch 188; see:

(The rhel xterm is apparently based on patch 179).
