  $> python fail.py p regularization-parameter

Examples:

  $> python fail.py 1.5 0.    # will fail to converge because of NaNs
  $> python fail.py 1.5 1e-10 # will converge
  $> python fail.py 2.  1e-10 # usual Poisson problem...
  $> python fail.py 3.0 0.    # again NaNs...
  $> python fail.py 3.0 1e-10 # converges, but too slowly

------------------------------
Script

  $> python catch.py ... 

shows how to catch a divergence of Newton solver. User can take
a special action for an event (here - increase regularization).
