Plugin is spawning multiple flow server processes in different projects

When I run eslint configuration with this plugin in different projects there are multiple flow processes running as a result.

Only way to get rid of these processes is to stop them manually.


This is screenshot when I run linting in 2 projects.

Is there a mechanism to stop them automatically? I know that it is hard because you start server on first run and then use `flow check-contents` to keep this plugin performant.
