Only one is actually required, and then only if the OS ever leaves ring
0 (? have to try it in my kernel), as it is used to store the location
of the ring 0,1&2 stacks for ring chages, otherwise, the TSS is not
needed. In fact, I think SOP is enter PM and THEN create a valid TSS and
load the TR (that's the way I did it).

Hmmm, I don't know, but I think it's re-used (knowing MS, probably just
an index into an array).
