- Adds the `breakEvalOnSigint` option to `vm.runIn(This)Context`.
This uses a watchdog thread to wait for SIGINT and generally works
just like the existing `timeout` option.
- Adds a method to the existing timer-based watchdog to check if it
stopped regularly or by running into the timeout. This is used to
tell a SIGINT abort from a timer-based one.
- Adds (internal) `process._{start,stop}SigintWatchdog` methods to
start/stop the watchdog thread used by the above option manually.
This will be used in the REPL to set up SIGINT handling before
entering terminal raw mode, so that there is no time window in
which Ctrl+C fully aborts the process.
