Eric, It’s been a while, and I’m in the middle of a few other things, but you can apply the patchlet (I’m pretty sure that it still applies as-is or with minor variants) and see yourself! By the way, if you feel like immediately pursuing the thing yourself, thus patch + testsuite tweaks + sending the whole package to the mailing list for comments, by all means reassign the bug to yourself and go ahead!
