Maybe have d.m (and maybe other interactive and parallel-exxecuting scripts,
e.g. nviz) write its PID into the /tmp grass directory as stg like
'killmeonexit1234' where 1234 is the process PID, and upon exit kill all such
notes from Init.(c)sh.

bash has a huponexit option (activate with shopt) that sends a SIGHUP to all
child processes upon exit. Is this inherited from sh or yet another useful
GNUism? Equivalent in csh?
