Normally you should terminate tgtd with SIG_TERM.
Currently tgtd isn't catching this signal.
So, when you use SIG_KILL the shared memory, which was allocated, is not being cleaned up.
In this patch I tried to do the same as in open-iscsi -
clean up all the shared memory when stopping tgtd with SIG_TERM.
