Here's yet another new version of my dtrace script, with yet another probe -- one for failures in `IOAccelVidMemoryList::ReverseIterator::getPrevMemory()`. Based on what Markus said, I assume the failures will happen here, when its called from `IOGraphicsAccelerator2::freeWaitToPrepareVidMap(IOAccelMemoryMap*, bool, bool)`. Eric and Sorin, please test with this probe. If you've already started testing with a previous version and haven't yet had a crash, quit the previous version (using Ctrl-C) and run this one instead.
