apt-get hangs with bypass4netns

[AkihiroSuda]

$ nerdctl run -it --rm --label nerdctl/bypass4netns=1 debian:11

dnf also seems very slow

bypass4netns v0.3.0, nerdctl v0.23.0 (Lima v0.12.0)

applying fcntl options fixes this problem.
This patch is just a PoC.
I'm working on re-work of bypass4netns and I will send PR when the work is finished.

Thank you @naoki9911

[AkihiroSuda]

@naoki9911 May I ask the current status of this?

[naoki9911]

Sorry for waiting long time.
I reimplemented bypass4netns entirely and its implementation very differs from current released one.
https://github.com/naoki9911/bypass4netns/tree/ng-b4ns

Should I make PR for this issue seperately or PR for entire reimplemented bypass4netns?

[AkihiroSuda]

Thanks, feel free to just open a single PR for the entire work

[naoki9911]
