Well, just in case, I'm not sure that that's bad "poll" that causes
the malfunction - it just happens that switching back to old schema
solves the problem.. But you know it better. ;)

And, I guess, you know that that configure test under 10.3 fails
because of the *assertion* in system poll on NULL argument (I'm not
sure if the assertion is the expected result).

I just did it (with ktrace): yes, the built-in version doesn't use
poll, but uses select.
