Nit: Should this have a "= {0}"?
My sigaction(2) says:
On some architectures a union is involved: do not assign to both sa_handler
and sa_sigaction.
so it's possible that sa_sigaction is left uninitialised.
If I'm wrong (quite possible, it's 2am), then part 1 lgtm.
+ action.sa_handler = sigterm_handler;

+ /* block other interrupts while processing this one */
+ sigfillset(&action.sa_mask);

+ /* restart interruptible functions (i.e. don't fail with EINTR) */
+ action.sa_flags = SA_RESTART;
