Interesting. We found a similar issue and fixed it differently in PR #3337 - Note that PR was not accepted in whole. I like the technique used this this PR though.

-            kill_local(cd->child->pid, SIGKILL);
+
+            /* Send signal to the negative of the PID to send the signal to all
+             * of the children of that PID - the process group under it.
+             * Otherwise it is delivered to only that PID.
+             */
+            kill_local(cd->child->pid * -1, SIGKILL);
