...well, the interface change is more like:

	fooselect() -> foopoll()

...and the arguments and return values are different.  There's not
really much else to change.  It's one of those things like "well, there
are only so many ways you can do this, and there's one that doesn't
suck."  :-)

The changes required in the drivers aren't that large, but you have to
change everything that has a "select" entry point...

(For the record, I think common interfaces are a good thing, but this
is one of those that just Isn't That Important To Worry About :-)
