Thank you Corona688,
I have thought of blocking signal, but the problem is that the first application may throw new files while the second application is doing signal handing (and therefore delete those new files - after a file is processed, it is deleted); so I wanted when new signal arrives the second application would restart processing and discard previous actions.
After all, I found that my problem could not be solve asynchronously by signal like that because there are too much work need to done in handing a signal (I know that I could make it synchronously by getting back acknowledge from the second application - but I seem a little expensive). I might have to chose another approach.
Thanks you all for your replies
