-----------------------+----------------------------------------------------
 If I connect arm to my client-only tor node that's been idle for some time
 and has no connections open, arm gets confused and thinks there's a socket
 listing problem.
 {{{
 [ARM_NOTICE] Unable to query connections with sockstat (bsd), trying
 procstat (bsd)
 [ARM_NOTICE] Unable to query connections with procstat (bsd), trying lsof
 [ARM_NOTICE] We were unable to use any of your system's resolvers to get
 tor's connections. This is fine, but means that the connections page will
 be empty. This is usually permissions related so if you would like to fix
 this then run arm with the same user as tor (ie, "sudo -u <tor user>
 arm").
