[erlang-questions] recover from unexpected errors from inside NIF

AFAIk there is no good way to recover from unexpected errors inside
NIFs. You have to make sure to handle manually all extreme cases
inside NIF's code, because NIFs are run directly in scheduler thread
of BEAM, so any errors can crash whole BEAM.

If you have some unstable library and there is no way to make it
stable, I'd suggest using it through external program connected to
Erlang via port mechanism.
