some trick?

[benzmuircroft]

I read your README.md ...

You say:

Now, There is a more reasonable choice when you need to writing file frequently, only the last one will be kept, and it is dead fast beacuse some trick to avoid unnecessary operation.

question: what is 'some trick'?

I am interested because; right now I am using write-file-atomic in order to be safe when writing! I was wondering if it would be both safe and fast if I modified write-file-atomic to require fstorm?

Note: this would mean that multiple instances of fstorm would be running in the same process fighting to save the same files
