haha :)

No, seriously though. Here is how I imagine a transaction between a FE 
and GDB.

   -> GDB alerts FE it is ready for a command via "(gdb)\r\n"
   -> FE sends a single MI input command
   -> FE does I/O with inferior
   -> GDB sends an MI output command
   -> GDB alerts FE it is ready for a command via "(gdb)\r\n"

So, the only time a FE would know that it is ready to send a command is
when it reaches the "(gdb)". Is this the same model for you?

That's why I think the output

   (gdb)
   444-exec-continue
   444*running
   444*stopped...
   (gdb)

is better.
