As an application developer I'm primarily interested in my own code and not the L{1,2}/RAM handling in supervisor mode. As Bortas said, I don't believe interrupts have a substantial effect on the memory behavior of user-level code. And if the app is bound by disk I/O I don't think optimizations on RAM handling is going to have a great effect anyway.

Who said anything about "user-level code"? The emulator has to emulate _all_ code to be accurate. If you don't emulate into system calls, you have _no idea whatsoever_ what's in the caches when they return. The same thing for asynchronous interrupt handlers.
