@viazovskyi I would need to evaluate more thoroughly but I believe this
change has a check and reset concurrent issue. While you're altering a
volatile field (so the change will be consistent across threads in reading)
what is not guaranteed is the timing of when the check happens versus the
reset. This might need an alternative approach or a lock.
