exc_general_protection() and do_trap() both call show_signal(), which

You could've done some git archeology and could've found

  abd4f7505baf ("x86: i386-show-unhandled-signals-v3")

which explains why that ratelimiting is needed.

For example, if a shell script, in a loop re-starts an app when it
exits, and the app is causing control-protection fault. The log
messages should be rate limited.

I think you should be able to get where I'm going with this, by now:
please put a comment over the ratelimiting to explain why it is there,
just like the above commit explains.

Thx.
