Stopping all child threads/process with addShutdownHook #383

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
During abnormal termination (e.g., csight process killed) we need to cleanup by 
stopping any running child processes (e.g., mcscm/spin). This needs to be done 
using the addShutdownHook:

am-is-stopped

This is mostly relevant to csight, but can also be important in 
synoptic/perfume/invarimint, all of which use an external graphviz child 
process to generate models (which may take a long time).
