localhost connect sometimes fail on ci

[Jérémy Lal <kapouer@melix.org>]

Hi,

https://ci.debian.net/packages/n/node-nodeunit/

sometimes fail to connect to localhost:$port

where $port is random between 40000 and 60000.

Note that it does try both ::1 and 127.0.0.1 before throwing, so both are rejected.

I have no idea how to reproduce this in a local container.

Any suggestions ?

Jérémy
