+Fix multiprocessing regression on newer glibcs
+
+Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some
+reserved signal numbers between 1 and NSIG.  The `range(1, NSIG)` idiom
+is commonly used to select all signals for blocking with `pthread_sigmask`.
+So we ignore the sigaddset() return value until we expose sigfillset()
+to provide a better idiom.
