Content
One solution to fix this problem is to use pthread_sigmask() on the _read() thread to not handle SIGARLM. For example, the faulthandler uses the following code to not handle any thread in its timeout thread: #ifdef HAVE_PTHREAD_H sigset_t set; /* we don't want to receive any signal */ sigfillset(&set); #if defined(HAVE_PTHREAD_SIGMASK) && !defined(HAVE_BROKEN_PTHREAD_SIGMASK) pthread_sigmask(SIG_SETMASK, &set, NULL); #else sigprocmask(SIG_SETMASK, &set, NULL); #endif #endif
