This turns out not to be the case.  The kill worked but the tcpdump
was not reaped:
0  1105  5868  4363  20   0 431820 19000 futex_ Sl+  pts/2      0:17                                      \_ swantest
4  1105 18674  5868  20   0      0     0 exit   Z+   pts/2      0:00                                          \_ [tcpdump] <defunct>
4     0 19041  5868  20   0      0     0 exit   Zs   ?          0:00                                          \_ [sudo] <defunct>
4     0 19044  5868  20   0      0     0 exit   Zs   ?          0:00                                          \_ [sudo] <defunct>

So: this looks like a bug in stwantest.
