Is it possible to translate Python exceptions to C++ exceptions? This way,
you can automatic roll out of any C++ method, even blocking ones. Then,
instead of explictly checking for python exception after each c++ method
call, you wrap C++ calls with try/catch, and you get the wrapped Python
exceptions there.

This probably requires Qt compilatoin with exception support (-exceptions).
I would find totally acceptable to have the pre-SIP 4.2 behaviour in case Qt
is compiled without exception support.
