I'm not sure I like this.  It doesn't really seem to mirror what's  
going on.  The -interpreter-exec command hasn't finished, rather,  
it's asking - out of band - for some more information.  So sending an  
out-of-band message with this request seems cleaner.  Why do you want  
the extra (gdb) prompt?
