I've generally found that:

  realtime stop
  halrun -U

...fixes up most problems, but then I generally play around in user
space and not kernel mode.

Regardless, unless your problematic realtime module is required to test
your python script, just don't load it.  Simply starting the realtime so
HAL has a place to put pins and parameters is enough to do testing with
usermode python scripts.  If you do need some sort of input, you can
probably use existing and (hopefully) well behaved HAL components to
generate it (siggen, sim_encoder, streamer, etc) either by hand or with
a simple HAL file to use as a testbench.
