Well, actually if there's no diagnostic output, there won't be any GDB 
protocol traffic.... although you have to kill GDB in a particular way to 
make sure it doesn't try and leave the target in a halted state (which 
just quitting GDB alone with "quit" would do)

The best way to solve this, if you don't need any debugging, is t disable 
CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT in your application build which should 
make the program ignore anything from GDB once it starts running. Then you 
can quit GDB happily without worrying about it trying to stop your program.

After you "continue" your application, you will probably have to press 
ctrl-c twice and confirm in GDB to get it to hang up since the target 
would no longer be responding to GDB.
