Make sure we service the CFRunLoop on worker threads, since ports using CoreFoundation
will be scheduling garbage collections and heap sweeps using CFRunLoop timers.
This fix is a stopgap. Long term we need a better design for integrating GC tasks with
with the web worker run loop.
* workers/WorkerRunLoop.cpp:
(WebCore::WorkerRunLoop::runInMode): Instead of sleeping forever, calculate a better
wakeup deadline by asking the CFRunLoop when its next timer will fire. Then, when a
timeout occurs, call CFRunLoopRunInMode (with seconds=0) to service pending timers.
