Well, I missed the tip about it being a loop, to be honest.  And I'm not
familiar with some of the PPC and Mac-centric things about that code.  
But this fragment:

00000094: 7C000026  mfcr       r0
00000098: 54001FFE  extrwi     r0,r0,1,2
0000009C: 68000001  xori       r0,r0,$0001
000000A0: 981C0000  stb        r0,0(r28)

looks suspicious.

0000009c: li r0,0

might go a long way toward fixing the problem, but I don't know what 
extrwi does.

(Windows threads fall off the end of the thread function to exit.  Apparently
Mac threads set a flag, or at least this one does.)
