+\ exit-smi is tricky. It replaces the SMM saved state with the
+\ current Forth engine state so that the "smi-return" returns
+\ to the caller of this word as if nothing happened, expect that
+\ the system is no longer in SMM state. This is used in only
+\ one place - the Windows "go to S3 power state" code. It's
+\ needed because the Geode hardware won't suspend from SMM state,
+\ ignoring the "2000 18 acpi-l!" (actually the machine code
+\ equivalent) in resume.bth. So we get out of SMM state, staying
+\ in Forth, then call the Forth suspend word that invokes the
+\ low-level suspend routine. Doing it this way, instead of writing
+\ new machine code, is easier, in part because it also make its
+\ easier to return to Windows upon resume. The ACPI resume interface
+\ requires that the final transition be done in real mode; we can
+\ do that from Forth by calling rm-run .
