�TimeoutReportReactorz�
A reactor which is just barely runnable and which cannot monitor any
readers or writers, and which fires a L{Deferred} with the timeout
passed to its C{doIteration} method as soon as that method is invoked.

Ignore the reader. This is necessary because the waker will be
added. However, we won't actually monitor it for any events.
Nr r r r r r { � z TimeoutReportReactor.addReaderc C s g S )z�
There are no readers or writers, so there is nothing to remove.
This will be called when the reactor stops, though, so it must be
implemented.

If there are no delayed calls, C{doIteration} is called with a

If there is a delayed call, C{doIteration} is called with a timeout
which is the difference between the current time and the time at
which that call is to run.

If a delayed call is scheduled and then some time passes, the
timeout passed to C{doIteration} is reduced by the amount of time
which passed.

If there are several delayed calls, C{doIteration} is called with a
timeout which is the difference between the current time and the
time at which the earlier of the two calls is to run.

If a delayed call is reset, the timeout passed to C{doIteration} is
based on the interval between the time when reset is called and the
new delay of the call.

If a delayed call is re-delayed, the timeout passed to
C{doIteration} is based on the remaining time before the call would
have been made and the additional amount of time passed to the delay
method.
