No, the idea is to make a dumb API call when the token expires, assuring that all simultaneous clients are stopped.
Anyway, do not worry, in the worst case of two simultaneous clients trying to refresh an expired token, only one will succeed.
Your application should be ready for failed API calls because those happen much more frequently due to outages of the API server. That is very common with Facebook, so you should be able to deal with those failures.
