On seconds thoughts, I looked at the dump.log carefully, i.e.

(I'm thinking aloud...)

...
(00.026529) 5840 fdinfo 4: pos: 0xffffffffffffffff flags:
100000/0
(00.026547) Dumping path for 4 fd via self 53 [net:[4026532332]]
(00.026557) Error (files-reg.c:349): No directory for original file
found in net:[4026532332]. Unsupported file.
...

=> /proc/5840/ns/net -> net:[4026532332]

The PID 5840 is really the "tcp-howto" client process, so 
I would not need its netns space and not sure how you will
close this file. I'll leave it for you guys to figure...I think the only
time this file is closed/removed if your kill the PID

Thanks for all your help.
