The comment should be "caller should look at revents", not
"rtnevents".  It's setting rtnevents, based on the values of revents,
so revents is what is being read.  Also, it seems like you could
compare against i, not *nsds, and avoid having to dereference a
pointer, but I can't imagine that really matters in this sort of code.
 In concept the change seems fine though.
