PosixReactorBase.runUntilCurrentto get invoked.
has a slightly different model of iteration, though: rather than have each
iteration process the thread queue, then timed calls, then file
descriptors, each callback is run as it is dispatched by the CFRunLoop
observer which triggered it.
So this waker needs to not only unblock the loop, but also make sure the
work gets done; so, it reschedules the invocation of
runUntilCurrent to be immediate (0 seconds from now) even if
there is no timed call work to do.
|Method||doRead||Wake up the loop and force
runUntilCurrentto run immediately in the next timed iteration.
