Any ideas?
My guess is that this has something to do with how your VOP_PAGEIN
entry point is implemented. I did some poking around in Preview with
GDB and it seems that it memory maps the image file (using mmap).
[NSBMPImageReader getByte] then reads the file by reading the mapped
memory.
Unfortunately I don't have a recommendation for how you might
implement VOP_PAGEIN given your current I/O design. I'd have to
study the problem in more detail than I have time for right now.
