Not exactly: If dumpcap were somehow to hang before doing the pcap_open and
then dropping the capabilities, it might be necessary to exit the (parent)
wrireshark to kill the (child) dumpcap.

I completely agree; The only concern I had was the small window during which a
signal from wireshark to dumpcap will fail. Since a dumpcap hang during this
window is unlikely, and since I believe exiting wireshark should kill any such
hung child process, I think the current code is OK.
