Running my Tor relay under valgrind with all the config options that
Yawning's sandboxed Tor Browser turns on, I see:
{{{

(This is the Tor from my bug20423 branch, which is commit caf742287 from
close to the edge of maint-0.2.9 plus two hopefully irrelevant commits --
so I am calling the version 0.2.9.5-alpha.)
