This task will allow you to toggle in the background, and check the current process limit value for Android. Found under Developer Options.
- Current Tasker version (5.8.3+) can't toggle that option, due to lack of the 'android.permission.SET_PROCESS_LIMIT' permission on its AndroidManifest. But the request is done, and accepted by the dev. So, as I don't know when this will be implemented officially, here you can download a test build that the dev sent to me, including the required permission, if you need it to be implemented in your projects asap.
