Check out the lib/system/posix.cpp module in k7. It creates a "file"
object that has an internal field set to a FILE* pointer. This object
is returned from the fopen function.
If you try to sniff the object in JS, you'll just see {}. But in C++,
you can get at the internal field. That's how the fread/fwrite
functions work.
