Okay Rich Felker, I was confused because the implementation in Musl
seems to look it'd would make syscall users that block cancellation
points. So, if GLibc does something similar to your solution they
would have to explicitly block cancels in the syscall function to
preserve compatibility (and in the future GLibc might possibly
consider moving over to making syscall automatically cancellable for
blocking system calls but that'd be a separate issue)?
