 Noticed something else with this:
 
 "step" does the right thing.  It executes the line and immediately
 returns back to the current stack frame.  "next" presumably goes down
 into it.  This is backwards from how gdb does it.

+Hmm, not entire right.  Here's a session using "next":

+You can see that the "finish" command has no effect.
+
+For contrast, here is a session in which I run "step".  It also
+eventually gets into the instruction mode:
