I think what's true now is what's always been true. The comment is a bit confusing, though. The two kinds of stopped are inside do_signal_stop() and inside utrace_stop(). In the former, it is inside the signal-checking loop and will check again. In the latter, utrace_stop() ends with a call to recalc_sigpending(). Thanks, Roland
