Well, I agree that it *could* break things, but considering that at
least glibc does the sign-exitension, any code that puts a large
number in the 'timeout' field would *already* have broken.

Which is why I think we should first try to fix the system call
interface - because it's the simpler patch, and it's the
RightThing(tm) to do from a standards standpoint. It's also almost
guaranteed to work, exactly because of how glibc already does that

But if something does break - however unlikely and perverse the code
has to be to be able to do that - we'd clearly have to undo that "just
fix sys_poll()" and use Thomas' patch to have a compat_sys_poll()

I just don't like the notion of doing that silly compat thing when it
really shouldn't be needed to begin with.
