And we now have a "shell" mechanism that also wants to do some process management. This is fundamentally about ctrl-C and ctrl-\ hooks because the native shells turn those into signals.
As a data point, the primary use case I gathered and reported by some customers using sun.misc.Signal is the ability to intercept control-C. SIGTERM, SIGKILL, SIGTRAP are also intercepted in addition to SIGINT
