That is a question. But actually I think sigio might be fairly
portable -- at least the first hit I found was for someone complaining
that it wasn't working on Linux (due to a bug) and this broke their
app which worked everywhere else.
In any case this would be a feature which if it didn't work would
leave us just where we are today. That's another advantage over trying
to do something with sigurg which would be far more likely to cause
headaches if it behave incorrectly.
