It's still inexcusable. The security update should have been immediate and separate.
What this doesn't excuse is disclosing the iOS bug before all fixes are ready. THAT was the major scrweup.
It was their decision to put the fix in 10.9.2 which is the problem. I agree rushing 10.9.2 would have been bad.
For quite a serious vulnerability, which requires removing one goto statement to solve? I am not sure by what standards that is a good response time. There is surely something wrong with Apple's procedures here.
