Bug 440230 fixed a couple of 16-bit reference counts that were possibly exploitable, this is a followup to that bug to figure out what to do in the much less likely case where a 32-bit reference count overflows. On 32-bit systems that requires a leak, on 64-bit systems it's possible to overflow w/o a leak (though not really trivially). So here we should figure out if and how to deal with the remaining parts...
