That's why it grabs a local copy of the sigcounter at the start of
that block of code, like this:

		struct sigcounter counter = sig_state.signal_count[i];
		uint32_t count = sig_count(counter);

so if you get a signal while in that loop then SIG_PENDING() that time
round may evaluate as false, but the pipe will be readable, so you'll
come back into this code again, and the counter will have incremented,
which means the blocked counter will now be set.

Cheers, Tridge
