7.2 is 2.4.7-ac ish, 7.2 + errata is 2.4.9-ac ish

Bollocks. I get regular mails from large numbers of people who are stuck
at 2.4.12/13-ac and are hoping I'll do an update because their machines
die in hours or run 25-50% slower with 2.4.1x.

2.4.1x VM code is performing better under light loads but its absolutely
and completely hopeless under a real paging load. 2.4.17-aa is somewhat
better interestingly.
