第一个问题这两天在考虑中，fastring 在多线程环境下复制确实不安全，应该用原子操作，调用 base/atomic.h 提供的 atomic_inc 与 atomic_dec 即可。可以提一个 PR。
Json 中的引用计数也没有使用原子操作，则是出于性能上的考虑，一般不会在多线程中复制 Json 对象。
第二个问题可能不需要考虑，推荐使用 jemalloc 进行内存优化。

替换全局的 operator new，operator delete，使用 jemalloc, tcmalloc 这类库应该就可以了

allocator 显然应该是可替换的，标准库的容器几乎都支持（除了 std::array 以外）。
fastring 的问题多了去了，不如用 rocket::cow_string 吧（逃
