I fail to see how it would be useful. RSA is such a slow operation that
doing it in userspace is efficient and safer.

So you're talking about the kernel side.. I was talking about userspace
perspective on the syscall. It would be rather odd to let a syscall
block other applications involuntarily (and thus achieving synchronous
action in your meaning)..
erface for userspace programs because it relies on
signals and thus can't be conveniently put into shared libraries..
