Sorry. I can not get you. Why jiffies counter is not sufficient to make cache names unique? And why is it a fragile approach?
Can you share your advice with us?I read your latest commit. In your commit, the ida is used to make cache names unique. It is a good approach if it can fix this problem.
The approach of jiffies seems clumsy. But it seems to be able to fix this problem, too. I can not see any risks about this jiffies appraoch.
