Réf. : RE: [LCP]Signal handler question

[David Filion]

But what about when I jump out of the signal handler, am I still in the signal
thread or am I back the normal thread?

Basically, once your sig handler is hit, you are in the signal "thread".
Anything you do before returning is under the rules/restrictions of signal
handling.
