I can't - I don't know why npviewer.bin is killed by SIGTERM immediatelly
when it socketcall to [::1]:6010 in Linuxulator and why it works
normally when it socketcall to 127.0.0.1:6010. I remember when I had
FF 7, Flash works with ::1 first, but Linuxulator not yet have any length
checks at those times as it have now (or perhaps other recent fixes).

This is not the case, all my ports which have IPv6 capability
are builded with IPv6 as the system too.
