When a signal is sent to a process by kill(), or is generated by
setitimer(), which thread handles it?

I couldn't find it in SUSv3. On Linux with NPTL only the main thread
seems to receive it.

sigprocmask must be used only in single-threaded programs, right?
But pthread_sigmask brings a dependency on pthreads. Does it mean
that it's impossible to write code which blocks signals temporarily,
doesn't create a dependency on pthreads, but if it's linked with
another library which uses pthreads then they still work?
