Keep this value to x Any thread could be at any step in this process Anytime, and they're able to step on one another when a shared source is associated. The point out of x may be transformed by One more thread over the time among x is staying browse and when it's prepared again.

The great factor about depend() is usually that it would not split your code or have to have you to definitely throw an exception when x isn't found.
I assume with the use situation that you choose to describe you want The complete file in memory, and this way you don't corrupt the file just in case your plan terminates in advance of it's time to save lots of and exit.
A race affliction happens when two or even more threads can entry shared information and so they attempt to change it at the same time. As the thread scheduling algorithm can swap among threads at any time, you don't know the get in which the threads will make here an effort to obtain the shared facts.
