For those users experiencing xfce4-xfapplet-plugin causing load to be 100%, please file a new bug report. This can be done after experiencing the issue using "ubuntu-bug xfce4-xfapplet-plugin".
Since the original issue, not being able to restart gnome-system-monitor when used with xfce4-xfapplet-plugin in the panel appears to be resolved in the latest release, Ubuntu 10.04, I am closing this report.
