This is in place now for 
<https://ci.libreoffice.org/job/gerrit_linux_clang_dbgutil/> for a 
while, and appears to be effective so far.

Just now I also enabled it for 
<https://ci.libreoffice.org/job/lo_tb_master_linux_dbg/>, changing the 
build shell command at 
<https://ci.libreoffice.org/job/lo_tb_master_linux_dbg/configure> from

> ${LODE_HOME}/bin/tb_slave_wrapper --branch=MASTER --os=Linux --real --name=Jenkins_Linux_Dbg 
> --distro-config="dev_master" --check --docs

to

> --name=Jenkins_Linux_Dbg --distro-config=dev_master --check --docs"

(That job is restricted to tb75-lilith, so will have a recent enough 
lode repo with a known-working bin/kill-wrapper executable checked out.)

Build <https://ci.libreoffice.org/job/lo_tb_master_linux_dbg/28606/> had 
been aborted with

and the following 
<https://ci.libreoffice.org/job/lo_tb_master_linux_dbg/28607/> had 
failed UITest_chart in a way that smelled like a leftover soffice.bin 
again, and indeed there was a matching zombie on tb75 (which I killed 
manually).
