I don't have any issues (yet) running it with the sandbox on, but I
agree it's good to test it extensively beforehand and depending on the
stability wait until the Tor Project defaults to it.

As mentioned earlier in the thread: I don't think it should be default
until we have
found it to be stable enough. I experienced several "sandbox violations"
when running
this in the last days. Is this good? Is this bad? I had no chance to
investigate this so far.
It also goes against torproject recommendations, as they consider
sandbox (seccomp) in
tor to be an unstable + testing feature, disabled by default.
