watch method

Stream<ProcessSignal> watch()

Watch for process signals.

The following ProcessSignals can be listened to:

• ProcessSignal.SIGHUP.
• ProcessSignal.SIGINT. Signal sent by e.g. CTRL-C.
• ProcessSignal.SIGTERM. Not available on Windows.
• ProcessSignal.SIGUSR1. Not available on Windows.
• ProcessSignal.SIGUSR2. Not available on Windows.
• ProcessSignal.SIGWINCH. Not available on Windows.

Other signals are disallowed, as they may be used by the VM.

A signal can be watched multiple times, from multiple isolates, where all callbacks are invoked when signaled, in no specific order.
