Re: non-preemptive tasking on GNAT 2020 Windows 10 multicore AMD

So, I am puzzled. Nothing I do makes any different whatsoever in how the little test program runs. Setting the scheduling police, setting the task individual priorities to Max_Priority, running as admin, setting pragma Locking_Policy(Ceiling_Locking), etc. Nothing stops it from this exact output (except a slight variance in the X number)

one
two
 24 cpu's
task one died, x= 397682
Task two done, y= 1000001
^C

Kind of disheartening, and I'm not sure where to go next. I don't so much require a non-preemptive scheduler, but my inability to affect any behavior at all for teh tasking is really wierd, and seems like a bug of the underlying system. Anyone have any ideas? Is there some fundamental flaw in my little test program I'm missing?
