How are you going to allocate large bitmaps?
   malloc(sizeof(TSS) + bitmapsize) is easy but swapping the result
   isn't.

Actually, it's fairly easy, thought a bit expensive.

   (SS)	// h/w switch would also wasting switching a zillion segment
	   // regs and the LDT

Actually, this is necessary to support user-settable LDTs.
