According to Nathan J. Williams lib/libpthread/arch/sparc*/pthread_switch.S
need maintenance (Volunteers?):

1) make pthread__switch more like pthread__locked_switch, and store
   into PT_UC of the old thread after the stack switch. Done a long
   time ago for several architectures, but never done for sparc.   
	 
2) In the code paths that write to PT_SWITCHTO and PT_SWITCTOUC, make
   PT_SWITCHTO set *last*.
      
3) Expose the return point of pthread__locked_switch from (1).
