Review comment:
       Hi @eolivelli 
   I changed the method to run in a single thread. Could you review it again?
   
   After deep thinking, I think creating an executor that chooses thread by TC 
id is better than running in a single thread. but I think I need to do it at 
another PR to avoid making this PR more complex.
   
   Let me know what you think! thanks~
