Worst (but frequent) case here is that all or most of the chunks in the repo need to get recompressed, thus storing all chunk ids in a python list would need significant amounts of memory for large repositories. We already have all chunk ids stored in cache.chunks, so we now just flag the ones needing re-compression by setting the F_COMPRESS flag (that does not need any additional memory).
