# This is a place where you can put code that should be executed once,
# and accessed by several different threads. When it is called, it will
# block the thread until the calculation has been completed, and memoize it.
#
# This means all threads that call the same method will wait for the same result,
# that is only carried out once. Think of it as a traffic light; cars arrive at the
# red light at different times, wait, and all take off together once it turns green.
