Thanks for the analysis!

At first look that `inflaterCache` seems not particularly order sensitive ("give me a deflater, any will do"). In fact in the past this used `j.util.Stack`.

I may take a look at this as a follow up. The change to `ArrayDeque` may have been motivated more by synchronization concerns.
