Signal handling in multiprocessing children is not working correctly #103

Open joshschmelzle opened 2 years ago

joshschmelzle commented 2 years ago

There is a scenario where a child process spawned by the main multiprocessing PID dies and profiler does not stop. Need to investigate ways to better handle signals and stop profiler if there is a problem in one of the other processes.

More useful reference code here for working with multiprocessing.
