Yes doctest can be asked to HALT_AT_NTH_FAILURE, including HALT_AT_FIRST_FAILURE. Merely (1) construct an object to replace stdout, so that (2) you can redefine the stdout.write calls of doctest, so that (3) you can filter the bytes written there, so that (4) you can raise KeyboardInterrupt, so that (5) you can exit when you please. Not a documented feature. Mostly works all the same.
