Let's hold off on this for a little bit and use Vlad's new stuff.

The above is better, except you really should use mi_gdb_test even if
you don't care about the result.  It's important that every time you
send a command to GDB that produces output, you also consume that
output.  Otherwise, you can get this behavior:

-> -break-insert $end_of_proc
-> -exec-continue
<- ^done
<- (gdb)
  Oops, that looks like the default case, something must have gone
  wrong with -exec-continue.  FAIL.
<- ^running
<- ^stopped
<- (gdb)
