[Kill randomly at various points in source code for testing] Summary: This is initial version. A few ways in which this could be extended in the future are: (a) Killing from more places in source code (b) Hashing stack and using that hash in determining whether to crash. This is to avoid crashing more often at source lines that are executed more often. (c) Raising exceptions or returning errors instead of killing Test Plan: This whole thing is for testing.
