// Test whether no race conditions are reported on std::thread. Note: since
// the implementation of std::thread uses the shared pointer implementation,
// that implementation has to be annotated in order to avoid false positives.
// See also http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html for more
// information.
