I welcome this bit in particular very much.  I know I was confused
by this when I first learnt about expedite registers.

Yes, but not through current_inferior.

Please change this bit to:

-      struct inferior *inf = find_inferior_pid (ptid_get_pid (ecs->ptid));
+      struct inferior *inf = find_inferior_pid (ptid_get_pid (inferior_ptid));

Although inferior_ptid is pointing ecs->ptid at this point,
current_inferior asserts if the inferior is not listed, which does happen today.
See this just below:

     /* We may not find an inferior if this was a process exit.  */
      if (inf == NULL || inf->stop_soon == NO_STOP_QUIETLY)
	normal_stop ();

I've got  patches that fix the targets to not do that, so I can
revisit this bit by then.
