   No.  You can have a heap allocator in the core server or in
the kernel.  It doesn't matter.  The point is, that it's explicitly
outside of the scope of XAA.  Having it in XAA would imply assumptions
that would limit what you could do with it.

    I don't care how you implement it.  It's abstracted to the point
where XAA doesn't care how you do it.  XAASurfaces are nearly opaque
outside of the driver.
