Comment (by arma):

 Speaking of atomic, there's an intriguingly related ChangeLog entry to Tor
 itself in 0.3.3.1-alpha:
 {{{
     - Use stdatomic.h where available, rather than mutexes, to implement
       atomic_counter_t. Closes ticket 23953.
 }}}
 But on first glance it looks like that's headers, not the library. But,
 does that mean that if Tor Browser builds Tor on a system with libatomic
 headers, then Tor Browser's Tor will expect a libatomic it can use?
