I was maybe not clear enough.  Please don't write:

	while (++timeout) {

That doesn't make sense as a loop.  It looks like you are trying to
loop UINT_MAX times.  Put the ++ and the limit on the same line.

There is only one real bug in my review but there is just a lot of clean
up left.  Can you have a co-worker review your patch before resending?
The patch 1/6 looks pretty good now but I haven't seen patches 2-5 so
I'm worried there is a lot of cleanup left to do.
