Hi Nathan,

Thanks for your help.  I applied the two patches as you suggested.
They fixed the first of the two bad sys_restart return values, but the
final one (quoted above, for what it's worth) still returns -512.
When I use the -d -v switches to restart, it appears to work (no error
messages are returned), but only the main thread is restored while the
second thread is not.
