f6ad5edab0 UserspaceEmulator: Make mmap'ed memory track read/write protection 
Here's the first time we get a taste of better information than the
real hardware can give us: unlike x86 CPUs, we can actually support
write-only memory, so now we do!

While this isn't immediately useful, it's still pretty cool. :^)
