) Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some reserved signal numbers between 1 and NSIG.

So we ignore the sigaddset() return value until we expose sigfillset() to provide a better idiom. (cherry picked from commit 25038ec) Co-authored-by: Antoine Pitrou <[email protected]>
