Ari,

All driver implementations are supposed to flush to disk when the
datasource/dataset is destroyed.  If they don't, it is a bug in the
driver implementation and should (IMHO) be addressed there.

A problem I think we have had sometimes in the swig bindings is
that confusion about reference counting has resulted in the
datasource/dataset objects not being properly destroyed.  But I
think we also need to solve the root of this problem (if it still
exists), not work around the symptoms.

Best regards,
