Could you say a bit more on the conditions under which this happens? With artdaq-demo v3_04_00 installed on mu2edaq01 (~jcfree/artdaq-demo_v3_04_00), if I log in and set DAQINTERFACE_PROCESS_MANAGEMENT_METHOD to "direct", none of the following three scenarios causes leftover processes after I cd into ~jcfree/artdaq-demo_v3_04_00:
- Simple execution of ./run_demo.sh
- Execution of ./run_demo.sh where I kill the window in which DAQInterface was launched while it's still running
- Modifying the ToySimulator so that it will hang on stop, and then executing ./run_demo.sh where a stop timeout occurs

I've been seeing many instances of processes, especially datalogger, being left over after a run_demo run using direct process management in DAQInterface.
I'm not sure if this is a failure in the DAQInterface cleanup logic, or artdaq handling a signal and not exiting as expected.
