SIGINT/Ctrl-C while profiling should gracefully finish

[mmarchini]

SIGINT/Ctrl-C while profiling should gracefully finish the profiler and write the results to stdout/file. Two SIGINT/Ctrl-C should stop the program.

Hey! Just to clarify, is it about close the debugger listener after a command right?

[mmarchini]

Yes, it would stop the profiler, capture the data and send to stdout/file (depending on flags). perf has a similar behavior.

I take a quick look today on this but seems not supported by nodejs as well. Just local close could be done, maybe sent another signal and provide in docs a default handler to client use? (do not sound good for me).

Maybe can be a great feature on nodejs, what do you think?
