The timer will be fired asynchronously to handle time management flags, while other threads are searching. This implementation uses a thread waiting on a timed condition variable instead of real timers. This approach allow to reduce platform dependant code to a minimum and also is the most portable given that timers libraries are very different among platforms and also the best ones are not compatible with olds Windows. Also retire the now unused polling code. No functional change. Signed-off-by: Marco Costalba <mcostalba@gmail.com>
