On glibc and musl, sleep() discards the fractional remaining time.
If the first signal interrupts sleep(3) after 2.1 seconds, it returns
zero with about 0.9 seconds still in the budget, so this can fail before
the second signal arrives.
Use nanosleep() and retain the full remaining timespec, or wait against
a monotonic deadline.

Verdict - Needs revision
