* Figure out why it's failing (TDSK) on some boxes. (Might be solved.)

* Is there a race while allocating a handle? Like this: a call to
	xms_alloc_xms, interrupt occurs giving control to interrupt
	routine that calls xms_alloc_xms -> bang!


----------------------------
For much(?) later:

* XXMS support.


----------------------------
Never, unless:

* A 286 version, unless somebody can explain how to switch back to
	real mode on one those.
