OK by me.

I thought about platform-specific messages, but it's not clear to me
whether our translation infrastructure will find messages that are
inside #ifdefs ... anyone know? If that does work, I'd be inclined
to mention ulimit -n on non-Windows and just say nothing about that
on Windows. "File descriptor limits" seems too unhelpful here.
