No, "it didn't work" for you because you killed the program before the signal handler was called.

Have you tried the one-liners yourself? (I ran them on Ubuntu Linux, in case that makes a difference.)

Are you saying you are observing different behavior than I am? If so, what is that behavior?

If you're saying it's not a buffering issue, what do you think is causing the different behavior of the first two of my one-liners above?
