@ManagedResource("Reaper for external processes")
public class ExternalProcessReaper
extends AbstractReaper<ExternalProcessReaper.PIDGroup>
```
A reaper that can terminate external processes by force. These processes are defined by their process ID (PID).
If there are several potential PIDs that this process might have the reaper keeps tracks of them in a ExternalProcessReaper.PIDGroup until it is not ambiguous anymore which one to kill. There are two possibilities:
- The ExternalProcessReaper.PIDGroup shrinks by terminating the processes in other ways until only one PID is left.
- More ExternalProcessReaper.PIDGroups get enqueued until the number of identical ExternalProcessReaper.PIDGroup is the same as the number of PIDs tracked.
