That's potentially a common problem, and "cat *" is an overly-simplified example. Either you force the "plugin" to say whether it wants to be cached or not, or you cache everything, because there are going to be plugins like "tar -xjp" for which caching is a HUGE increase.
Ok, I accept the argument.
