> Is there a standard way in WebCore to get a signed difference of unsigned values?  Should I add an ASSERT that checks for overflow?

Generally with unsigned values check which number is greater before doing any subtraction. Not sure if that’s helpful in this case. Since you already posted a new patch I’m assuming you did something. I’ll see when I get a chance to review.
