The problem arises that I have a multithreaded application (only 2 threads) and the SIGPIPE signal seems to get delivered to the PROCESS and not the THREAD.

Yes, this is how it works in Darwin/OS X.

when I tried signal(SIGPIPE, SIG_IGR) or sigignore(SIGPIPE), or even sigaction(...) to ignore the signal from one thread, it still got delivered... and I got stopped in the debugger.

Beware of the debugger. I think it will 'see' signals even if your program is ignoring them.
