 When I test Tor with $HOME unset, I see the following error:
 {{{
 options/validate__uname_for_server: [forking]
   FAIL ../src/test/test_options.c:507: expected log to not contain entries
 Captured logs:
     1. warn: "Couldn\'t find $HOME environment variable while expanding
 \"~/.tor\"; defaulting to \"\".\n"
     2. warn: "Default DataDirectory is \"~/.tor\".  This expands to
 \"/.tor\", which is probably not what you want.  Using
 \"/usr/local/var/tor\" instead\n"

   [validate__uname_for_server FAILED]
 }}}

 This test has been around since 0.2.8.1-alpha.
