Hi, I dont' know if this meet what you described, but I use a single line
to clean un-referenced shared memory.

x.sh:
#!/bin/sh
ipcs | awk '{if ($5 == ENVIRON["USER"]) system("ipcrm -m" $2)}'

Before applying 3 options posted by ade lovett into my kernel,
most heavy gtk programs like xmms, gimp, gnome-controlcenter...etc,
will die with whole X crashing. (I invoke X with gnome-session, what the
gnome document said) Thus I have to run x.sh whenever my X crashed with
share memory bodiz *shurg* /.\
