Review comment:
Add this operation just to Make AverageThreadTokens more accurate
- AverageThreadTokens: 1.00
Do not warry thread hang on this operation。
acquire_thread_token() just do a lightweight add operation without doing the
really thread assignment
inline void ThreadResourceMgr::ResourcePool::acquire_thread_token() {
__sync_fetch_and_add(&_num_threads, 1);
}
