ByteArray# can be passed to C functions as well. The only problem is
with mmap which cann't be implemented with arrays. mmap returns a
pointer to the mapped file which is outside the Haskell heap.

I am curious why FPS is implemented on top of ForeignPtr. ByteArray# based implementation should be faster and more space efficient.
I think the reason is C compatibility. A number of functions in FPS use ffi-bound C code (mmap, gz (de-)compression,...).
