If we are not obtaining any useful information out of the poll(),
such as is a fd busy or not, we do not need to do a poll() if
an immediate_wake() has been requested.
This cuts out all the pollfd hash additions, forming the poll
arguments and the actual poll() after a call to
poll_immediate_wake()

I don't think we need the new 'immediate_wake' member of struct
poll_loop. A 'timeout_when' of LLONG_MIN already means the same thing
(it's even documented in the comment).
OK. Cool.
I did not want to touch any of the timeout logic, so I added a member.
I will send a v3 which uses timeout == zero for this on Monday.
A.
Thanks,
Ben.
