RFC, fix for bogus timeouts in select()

[Andrew Lunn]

Hi Oyvind 

Did you debug this in detail. I don't see why your fix should help.
The only thing i could come up with is if selwait.wait() is returning
0 when both the condition variable is true and a timeout has
happened. But looking at the condition variable code i cannot see how
that would happen.

Can you explain in detail what is happening and why your fix works for
you?

        Thanks
                Andrew
