When I start for example the demo nodes for the node explorer with `./gradlew tools:explorer:runDemoNodes` and later terminate the gradle task with CTRL-C, the java processes of the nodes keep running.
This is counter-intuitive, I would have assumed that the processes nodes are terminated as well. It's problematic because the processes are not exactly light-weight.
This behaviour differs by OS, on Windows & Mac it's apparently not an issue.
I talked to Viktor Kolomeyko, he agreed to my suggestion that adding a shutDownHook that terminates the Processes created by DriverDSLImplementation.startOutOfProcessNode might be a good idea.
