+Subject: [PATCH 09/10] Fix invalid sigprocmask call
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The POSIX document says
+
+    The pthread_sigmask() and sigprocmask() functions shall fail if:
+
+    [EINVAL]
+    The value of the how argument is not equal to one of the defined values.
+
+and this is how musl-libc is currently doing.  Fix the call to be safe
+and correct
+
