Summary:
There can be multiple reports per line, especially when calling in a method which has itself multiple reports.
When reporting at the callsite, report only the issue with the highest severity (picked manually per type of event).
Deadlocks are not de-duplicated, as they are relatively rare and the info in mupltiple reports may be important.
