Log Message:
Pull up revision 1.57 via patch (requested by chs in ticket #1160):
define a new LWP flag which indicates that we're in the process of
doing a context switch.  use this on sparc and sparc64 to avoid trying
to access user memory (writing the register windows back to the stack)
in this case (since it's both unnecessary and wrong).
