Four days, actually!
The patch was first released on 10th December - and pulled within 24 hours.
They released the KB3024777 removal tool about 4 days later - but the problem was that about half the affected machines were blocked from actually downloading and running the tool.
MS has kept VERY quiet about that (I wonder why?).
The fixed KB3004394 patch wasn't released until the February season - and has worked fine, so far as I can tell.
