Maybe that relates to what I'm seeing on the async branch (and with Apple's
GDB) where the inferior can't accept input on the same terminal:

  -exec-run
  ^running
  (gdb)
  Enter value for n1: 5
  Enter value for n2:
  Suspended (tty input)

Where 5 has been entered by the user for the inferior.

I was hoping that GDB could tell whether the inferior was waiting for input or
not and pass any input it receives or process it accordingly (a problem I
have with Emacs is not knowing whether to queue an input for GDB or send
it immediately for the inferior).
