Just for the records - why my example with “apache2” process shows this behaviour.
It’s caused mod_perl - that one mangles apache's process name. See https://bugs.launchpad.net/ubuntu/+source/libapache2-mod-perl2/+bug/1008385 and a fix at https://bugzilla.redhat.com/attachment.cgi?id=567625&action=diff -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
