Comment:
Replying to [comment:12 tibbe]:
> `poll` sets `POLLNVAL` per FD so that should be possible.
Ok. In that case we could declare it to be a bug in the non-threaded RTS
that could be fixed by using `poll()` instead of `select()` and generating
correct error returns from `waitRead#`. Fixing it won't be a high
priority, though.
