+	 *
+	 * XXX This raises the question, whether we can do the same on
+	 * XXX sparc32 to get rid of fork_kpsr _and_ fork_kwim.  The
+	 * XXX answer is yes.  We stick fork_kpsr in UREG_G0 and
+	 * XXX fork_kwim in UREG_G1 (global registers are considered
+	 * XXX volatile across a system call in the sparc ABI I think
+	 * XXX if it isn't we can use regs->y instead, anyone who depends
+	 * XXX upon the Y register being preserved across a fork deserves
