For very slow removals the current bias sense timeout is sometimes too
short and unclamps the mic bias before the jack removal is properly
detected by the tip detect, causing a pop. As bias sense should be
tuned to deliver very few false positives, increase the timeout fairly
dramatically to cover all but the most exaggerated removals.
