My crystal ball says that redisplay isn't happening because Emacs
doesn't know that the GDB prompt has arrived. The call to sit-for
causes Emacs to check its input descriptors, "discovering" that there
is input.
Please look around in wait_reading_process_output, and see what is
going on there, before and after the call to sit-for. In particular,
does the call to `select' report that input has arrived from GDB?

I think it's not going to solve the real problem. If Emacs misses
some of the output arriving from GDB, it will miss it again under
similar circumstances.
