Maybe we should reconsider using it.. I'm not aware of any bugs in SIS, but yeah, it can be a bit complicated. If you do things like dsync where destination is also mdbox/sdbox, it's going to keep using the same SIS directory and updating the refcounts, which you probably don't want for backups / temp directories (solution: give different parameters to the two sides of dsync where the other side disables SIS).
