Comment 11 for bug 148454

Confirmed here with Ubuntu Hardy 8.04 fully update/upgraded and with htop 0.6.6 - (C) 2004-2006 Hisham Muhammad.
The htop list a lot of duplicate rows about the unique ( verified with ps command ) process, with different htop PID number:
/usr/sbin/console-kit-daemon (60 rows)

same for the unique process :
/usr/sbin/apt-cacher-ng (3 rows)
with different htop PID

Top works good and i see only a process for console-kit-daemon and for apt-cacher-ng

*** It seems that by default, htop lists each thread on a separate line, while other utilities don't. If you want to see one line for each process, hit F2, then enable the "Hide userland threads" option in the "Display Options" menu.

Works good

Hope this helps, thank you.
