Note that our allocator uses malloc() underneath. And I would think
that we do pass FILE pointers around too; AllocateFile works with FILE,
so any library that's using that method to get to files would be in
trouble (which they should, because it's the way to ensure we don't leak
files on transaction abort and also to ensure that the system continues
to work on the face of lots of open files).
