Any way to make assertion script wait until AfterRequest script finish?

In my mock service, I add AfterRequest script to allow save my rest request and response to SQLite db.

Some of my test case assertion script need read the request/response saved by AfterRequest script, but occasionally it fails due to the fact that assertion won't wait AfterRequest script. The log shows they're started execution at the same time.

I know I can manually put Thread.sleep in my assertion script, but it looks ugly. Anyone have a better solution?

Thanks
