Now Wireshark never closes - I select "Stop and Quit Without Saving" and the
capture stops but Wireshark just sits there. `ps` showed that Wireshark had a
zombie dumpcap child.

I attached to Wireshark with strace, and it's looping with the following:

poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN}], 3,
100) = 0 (Timeout)
read(4, 0x7fff53c119e0, 16)             = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(3, 0x23862e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN}], 3,
70) = 0 (Timeout)
read(4, 0x7fff53c119e0, 16)             = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(3, 0x23862e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=6, events=POLLIN}], 3,
30) = 0 (Timeout)
read(4, 0x7fff53c119e0, 16)             = -1 EAGAIN (Resource temporarily
unavailable)
recvfrom(3, 0x23862e4, 4096, 0, 0, 0)   = -1 EAGAIN (Resource temporarily
unavailable)

I eventually had to SIGTERM.
