I'm pretty sure the application is checkpointing correctly but we're still getting the odd bad workunit. Not quite sure what's causing it, but I'm going to keep looking into the problem.

This is happening in all the 0.14 compiled apps. Including the Gipsel app (which i think has a slightly different fix to the checkpointing problem). So I'm not quite sure if the issue is still checkpointing or if it's something else.

Pretty sure I found the issue.

At the end of calculate integrals there is:

        #ifdef GMLE_BOINC
                int retval = write_checkpoint(es);
                if (retval) {
                        fprintf(stderr,"APP: astronomy checkpoint failed %d\n",retval);
                        return retval;
                }
        #endif

So in the rare case that this is the last checkpoint calculated (and there hasn't been a new one from the next integral calculation or likelihood calculation), the app will recalculate an integral. I'm going to do another update because I think this should put the last nail in the coffin to this problem.
