this looks not ok as it effectivly doubles the number of passes over the whole file also there is no need for this, doing a single pass either you are done or you are not so its possible to know if all have been read. If the existing check for the last sidx is wrong then it should be fixed. also this patch only fixes the issue if seeking for a 2nd pass is supported [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Dictatorship: All citizens are under surveillance, all their steps and actions recorded, for the politicians to enforce control.
