Dear POSIX thread experts (i.e. Ingo and Ulrich),
I have a teensy question. Using the new Linux 2.5 threads + glibc/NPTL:
1. If a signal is delivered to a thread, is it masked for the duration of the handler in (a) just that thread or (b) all threads?
In other words, if I have 3 threads and SIGIO is not blocked in any of them, is it possible for my SIGIO handler to be called up to 3 times concurrently? Or is the blocked mask somehow shared?
Is the same thing true of SIGCHLD? SIGSEGV?
2. Is this true of POSIX threads in general, or just Linux?
Thanks, -- Jamie
