You want to know how many bit are left for some reason?  Is there some
user API that will break if we overflow and start allocating bits from the next
64-bit word? Or is this just the countdown for when you and I both have a nervous
breakdown trying to keep track of that many different option paths through the
machine check code :-)

Thanks for the tip about Ctrl-x to decrement a number in vim (Google
tell me Ctrl-a increments). Learned something new today :-)
