can this be reproduced as root user?

[mariux]

to answer my own question: yes it can be.. ;)

fact is... -u just executes mxqkill on behalf of the user... not to kill all jobs of the user... so -u is not supposed to be a filter... which is just badly documented... you need to add filter for group or job to actually kill..
