Comment (by toralf):

 I applied 02723814521e891260637764c236c9f9e5f429e2 here on top of the
 patched 1-4-0 stem - works fine, so is "DisableDebuggerAttachment 0" is no
 longer needed ?

 :-)

 For debug purpose I printed out all ipv6 connections I got from
 "get_connections(resolver, process_pid=pid, process_name='tor')":
 {{{
 ms-magpie stem-1.4.0 # /home/tfoerste/info.py
 ['proc', 'netstat', 'lsof', 'ss'] : proc
 ipv6 : ::ffff:78.54.157.219
 ipv6 : 2001:6f8:126f:11::26
 ipv6 : ::ffff:195.42.115.146
 ipv6 : 2001:858:2:2:aabb:0:563b:1526
 ipv6 : ::ffff:78.54.157.219
 ipv6 : ::ffff:78.54.157.219
 }}}
 and compared this to netstat it seems, that the beam connections (related
 to ejabberd) are still counted for Tor too, or :
