Use the --trace-sync-io flag to print a stack trace whenever a sync method is used after the first tick, excluding during the process exit event. (e.g. fs.readFileSync()) It does not track if the warning has occurred at a specific location in the past and so will print the warning every time. Reason for not printing during the first tick of the appication is so all necessary resources can be required. Also by excluding synchronous calls during exit is necessary in case any data needs to be logged out by the application before it shuts down.
