I already read somewhere that on FreeBSD, any thread can receive a signal, not only the main thread. I suppose that it should be the same on Linux, but Linux tries maybe to send a signal to the main thread if the main thread and other threads are calling a system call.

In this case, "_read" thread gets the SIGARLM signal and so its os.read() system call is interrupted. It means that os.read() is blocked at least one second, whereas wio.write() is supposed to send data to unblock _read() thread.
